When I was 23, I drove my parents' beat-up turquoise van to all 48 contiguous United States. Don't ask.
If I learned one thing, it's that America has a lot of crazy/hilarious/accidentally dirty signs (I'll let you decide which is which). I can't in good conscience promise that each of following is the best sign from each state... but it's probably in the running.
And no, I didn't take all these; I took some of them, but I Can Has Cheezburger? and BaconBabble deserve credit for some of the others.
