Teabaggers will soon descend on Washington for Glenn Beck's "Restoring Honor" rally, taking place at the site of Martin Luther King Jr.'s "Dream" speech, on its anniversary. What precautions should they take to avoid being murdered in this deadly town?

This map of Brooklyn shows the neighborhoods broken down by which type of ethnic cuisine dominates based on the Village Voice's restaurant guide. We're surprised Williamsburg isn't colored cheap-pizza-slices-and-taco-trucks. Here's the one for Manhattan. [Very Small Array, via]

Tourists suck. Use this map to avoid them in New York. Using Flickr's geotagging feature, Eric Fisher created this heat map showing where tourists took pictures versus where locals did. Red is tourists, blue is locals. (Click to enlarge.)

Going to San Francisco for vacation this summer? Make sure you check out this handy elevation map first. You can consult your guidebook for restaurants and bars, but this map shows you where to find all of the hookers! [FlowingData]

New York is getting a new subway map! It's the first redesign in more than a decade, and it mostly looks the same as the old map, but with new colors. Here are some of the big differences:

Need help finding a neighborhood to live in? The state Department of Health yesterday introduced its new cancer map that lets you see how many people in each census block have cancer, and what types of hazardous materials are nearby.

The BP oil spill is spread across an estimated 2,500 square miles, and is dumping at least 200,000 gallons of crude into the Gulf of Mexico every day. What would that look like in New York?

People have used math to determine that Lexington Ave. at 60th St. is the best place to catch a cab in Manhattan. Check out the sweet taxi "heat maps" from the New York Times and never walk anywhere again. [FlowingData]

It's national campaign stat-porn season again! Number muncher Nate Silver posted some of his magic maps this morning. These maps explain how Sarah Palin could be the 2012 Republican nominee for President!

This is a very popular map right now among the wonky liberal bloggers of the grown-up end of the internet. It is designed to make the electoral college and the Senate more "democratic." Which defeats the point of those institutions!

Here's a map of Park Slope—brave, bourgiest corner of Bourgie Brooklyn—where the streets are named for the rear-window college stickers found on parked cars. Odds are you'll find your own school somewhere. Maybe it was even your car!

Last week, we highlighted a scary county-by-county map that a commenter posted to #tips showing metastasizing unemployment growth. Today, it occurred to us that we'd seen a graphic like that somewhere before: A CDC map of obesity by county.

We've been updating our AP Layoffs List for three days with tips about layoffs in AP bureaus around the world. Here, we've organized and mapped them for you. View the national and global media carnage, below.

In February, we noted the sad decline of the once-posh, boutique-strewn neighborhood of NoLIta, where Gawker HQ is located. We sent the interns back to the streets and have a new report: more sales, more closing, and only some redemption.

Boing Boing came across this recent video of Franken drawing all 48 states (of the continental U.S., geography nerds) from memory at the Minnesota State Fair, and ever the paranoid types, wondered if Franken is faking it: "it would be easy to create indented trace-lines by using a pen with no cartridge in advance." Doubtful given how long and how often Franken's been doing this trick.

The landscape of the city changes with each passing day as retail outlets come and go and older buildings are torn down to make way for new developments. But if you want to see what NYC looked like way back in the day, the Mannahatta Project has an interactive map that allows you to zoom in on any section of Manhattan—such as Union Square, left—and then travel back in time to see what the same area looked like in 1609.

You won't be checking out the Blue Collar Comedy Tour this summer. Can we interest you in the White-Collar Criminal Tour instead? Click on the image above for the locations of a handful of white-collar crooks currently behind bars. Then all you have to do is use Google's driving directions to plot out your fun, summer road trip! (You'll have to check with each prison about visitation privileges, of course.) As you can see, it's an incomplete list. Email us at tips@cityfile.com and let us know who we're missing and we'll add them right away. [White-Collar Criminal Tour]

This is technically called a "horizonless projection in Manhattan" but it's basically a crazy bendy map of everything from 34th street down. Cool. [Here&There. Click to enlarge]

If there's anyone who grasps the secrets of cultural "buzz," it's Spatial Information experts employed in academia. There's a new "Geography of Buzz" map that scientifically proves that "buzz" is centered...where events are held.

This map of where famous sitcoms were set—on TV, that is, not in real life—isn't the most precise thing in the world. (We're going to assume the placement of Sex and the City on the Upper East Side is because Charlotte's character lived there?) But if you're a TV location scout and you're looking to showcase an NYC neighborhood that has yet to be ruined by round-the-clock shoots and national TV exposure, it should be a good place to start.
