Here's a random website you can scope out the next time you hear residents of New York brag about how they reside at "39th and 4th" or "119th and Lenox, home boy."

This nifty site is known as ExtendNY.com, and it extended Manhattan's street grid across the entire planet.  Enter your zip code or address, and find your intersections.

As an example, someone in Missoula, Montana is at 10,453th Avenue and 7,933th Street.  Someone in Nepal is at 12,958th Avenue and 2,134th Street.  And so on.
