I typed in "map of Maryland" into Google, and obviously the first hit is for the Google Maps link. So I clicked on it, and this is what came up (click to enlarge):
It's hard to tell, but the arrow is pointing a little southwest of Annandale. Annandale , Virginia.
I zoomed in, and yep. Definitely Virginia.
Oh, Hell no.
UPDATE: Hey wow -- this is on the first page of results for "fuck google" on Google. Neat.
UPDATE #2: I should note that Google has fixed the problem. Hurray!
