Has Chicago Lost its Blues Mojo?

"Sweet Home Chicago" ain't such a sweet home for preserving blues history. Which is a shame for a city that cashes in big on its long-running Blues Fest and bluesy clubs around town. Here are 3 seminal sites in jeopardy:

1. Muddy Waters' house - Last week, a big red "X" appeared on the brick two-flat at 4339 S Lake Park Ave, an early step in the demolition process. I wrote about Muddy's house - where legendary jam sessions broke out in the yard - a few years ago, when it was still in decent shape. Now the windows are boarded up and ominous yellow warning signs hang in front. Urbanist Lee Bey looks at whether everything gonna be alright in this article.

2. Chess Records Studio - While Waters, Howlin' Wolf, Bo Diddley and the Rolling Stones all plugged in at 2120 S Michigan Ave, this building also was on the chopping block until Willie Dixon's Blues Heaven Foundation bought it. (Dixon was the bassist who wrote most of Chess's hits.) Dixon's family opens the studio for tours most days, but it's ramshackle with few original artifacts on display. Still, when Willie's grandson hauls out the bluesman's standup bass and lets you take a pluck, it's pretty damn cool...

3. Blues Museum - Chicago has been trying to open a blues museum for years. The latest incarnation was in summer 2012, when the city floated the idea for a "Blues Experience" museum/nightclub downtown on State St. Cue the hemming and hawing. Meanwhile downriver, St Louis secured $6 million to build the National Blues Museum to launch in 2014.

Chicago needs to get its mojo workin', as in this live album when Waters and the Stones played the Checkerboard Lounge in 1981.

National Pie Day: 4 Things to Know

Today is a big one on the pie calendar. It's National Pie Day, as decreed by the American Pie Council. That means sweet contests and free slices around the country. Random info in honor of the occasion:

*  It's also the 4th anniversary of Indiana's law making sugar cream the official state pie. Only Florida (key lime) and Vermont (apple) take their crust as seriously and have passed "state pie" legislation. Oh sure, Maine, Massachusetts and Delaware list pie for a "state dessert" (blueberry, Boston cream and peach, respectively). And Oklahoma includes pecan pie as part of its "state meal." But c'mon: be bold and declare an official PIE.

*  President Obama has been top of mind since his inauguration two days ago, and pie is his favorite dessert. He forked into maple-caramel-sauced apple pie at his post-swearing-in lunch. He's also fond of coconut chiffon pumpkin pie, according to his college roommate's mom.

*  Norse Nook in Osseo, Wisconsin, routinely stays open during blizzards. The "Pie Fixes Everything" motto tells you why. Check out this Flicker group of Norse's banana cream, raspberry white chocolate and other sky-high pies.

*  To salivate over regional variations in flaky goodness, click to American pie: slicing across the country. Peanut butter, gooseberry, sour cream raisin...

Mmmm, pie.

Presidential Pets: Hippos, Badgers & Cows (Oh My)

As Bo Obama, the presidential pooch, settles in to his second term of posing for White House Christmas cards and greeting Blue Room visitors, it's a good time to reflect on his predecessors. There's Barney the terrier, who bit reporters for George W. Bush. And Clinton's furry pals Socks the cat and Buddy the Labrador. But others in the first menagerie have been a bit more peculiar:

*  Adams-Hoover alligators - The Marquis de Lafayette gifted John Quincy Adams with a gator, which Adams housed in the White House bathtub. A century later Herbert Hoover outdid him by having two pet alligators that waddled the West Wing.

*  Josiah the badger - In 1903, a girl in wee-town Kansas asked the visiting Teddy Roosevelt if he would like a badger. "I said I would," and so Josh (Teddy's nickname for his new pet) rode the train back to Washington with the prez, joining his hog, rat, macaw and one-legged rooster.

*  Pauline Wayne the cow - A Wisconsin senator gave Pauline, a bodacious Holstein, to William Howard Taft, who let her graze the White House lawn throughout his term. The trade-off? Miss Wayne provided milk for the first family.

*  Billy the pygmy hippo - "Hmm," thought rubber maker Harvey Firestone. "What'll I do with this pygmy hippo that's wandered onto my Liberian rubber plantation? I know: I'll give it to Calvin Coolidge!" For the record, Coolidge already owned a wallaby, a duiker and a raccoon.

DC's Most Peculiar Museums

The Smithsonian grabs all the glory, its multiple venues rising up around the Mall like an educational fortress. But where are the giant hairballs and handcrafted mayonnaise-jar bongs? Here:

DEA Museum - One minute you're watching a video called One Sniff Can Kill, the next you're admiring an array of tightly rolled doobies. The federal, taxpayer-funded Drug Enforcement Administration curates the wares (located in the agency's lobby), which range from counterculture propaganda to undercover pimp gear like rabbit-fur jackets. Read more here.

National Museum of Health and Medicine - You might want to go light on breakfast before visiting the brains, spines and other body parts in jars. The stomach-shaped hairball leaves a lasting impression, as does Lincoln's assassination bullet and bits of his skull.

Stabler-Leadbeater Apothecary Museum - Antique glass medicine bottles and Martha Washington's Scouring Compound line the shelves of the 1792 shop.

Woodrow Wilson House - While it's swell to see how genteel Washingtonians lived and socialized in this 1920s home, the chatty docents are the real draw. They spill the beans on today's neighborhood elite, everything from which ambassadors shack up in their embassies illegally, to spot-on directions to the Clintons' nearby home (recognizable by the muscular Secret Service dudes sitting out front in SUVs and staring you down).

DC's Top 5 Sites for Political Intrigue & Scandal

Whaddya know? They're all hotels.

Watergate - Perhaps you've heard of the chi-chi apartment-hotel complex on the riverfront? Hint: a little break-in occurred here in 1972, something to do with Richard Nixon and wiretaps. Monica Lewinsky, Ruth Bader Ginsburg and Condi Rice have all lived at Watergate, despite the sad 60s architecture.

Renaissance Mayflower Hotel - J Edgar Hoover ate lunch here every day for 20 years. John F Kennedy reportedly sampled the charms of the fairer sex here. And NY Governor Eliot Spitzer infamously rendezvoused with a call girl here (room 871).

Washington Hilton - This is where John Hinckley tried to assassinate President Ronald Reagan on March 30, 1981. Hoping to impress the actress Jodie Foster, the disturbed young man shot Reagan, his press secretary and an FBI agent near the T St NW entrance.

Westin Washington DC City Center (formerly the Vista Hotel) - In 1990 DC mayor Marion Barry was caught puffing crack cocaine in room No 727. The FBI had a surveillance camera inside that also captured Barry uttering his timeless quote - 'Bitch set me up!' - in reference to ex-model (and police informant) Hazel 'Rasheeda' Moore, who was with him.

Willard InterContinental Hotel - President Grant coined the term "lobbyist" here to describe the many political wranglers trolling the lobby. You'll still find quite a few of them in the hotel bar, swirling single-malt Scotches and determining your next tax hike.

This is part 2 of a week-long series on DC. Part 1 reveals where to see nuclear missiles, the gun that shot Abe, and 8 other awesome things for free.

Top 10 Freebies in Washington, DC

The spotlight swings to DC on January 21 for President Obama's inauguration. Just so happens I co-wrote Lonely Planet's new DC guidebook, so for the next week I'm going to post stories about the city. First up: my favorite freebies in town.

1. Smithsonian Institution - It's actually a collection of 19 museums, all gratis thanks to an eccentric Englishman named James Smithson (more on him later). Top draws are the rocket-fueled National Air and Space Museum and the dinosaur-and-diamond-stuffed National Museum of Natural History.

2. National Gallery of Art - It takes two massive buildings to hold the trove of paintings, and sculptures. Monet? da Vinci? Pollock? All here, plus a trippy tunnel connecting the two sections.

3. Lincoln Memorial - Massive Abe sits and gazes from his neoclassical temple. And you can stand spot-on where Martin Luther King Jr gave his 'I have a dream' speech.

4. National Archives - Gawp at John Hancock's, er, John Hancock scrawled across the real-deal Declaration of Independence. The Constitution and Bill of Rights unfurl alongside it.

5. Ford's Theatre - See where John Wilkes Booth shot Abraham Lincoln that fateful night in April 1865. The basement museum shows artifacts such as the murder weapon.

6. Capitol - Button-down guides take you through the mighty, white-domed sanctum of Congress, cluttered with busts, statues, frescoes and people in power suits.

7. Bureau of Engraving and Printing - Though the Treasury tour is about money, it won't be taking any of yours. Watch millions of dollars as they're printed, cut and inspected.

8. Library of Congress - The world's largest library is more than a stack of books. It's a museum with 500-year-old world maps, historic photographs, concerts and film screenings.

9. Kennedy Center - No dough for a big-ticket show? Fear not. The Millennium Stage hosts a free performance each evening at 6pm. Could be anyone from the National Symphony to a gospel group or Indian dance troupe.

10. Cultural Tourism DC - It provides free maps, apps and audio for DIY tours around the city that uncover civil rights sites, espionage hot spots and other historic places.
