Madison Avenue was not, of course, the only thing named after the former President and principal author of the US Constitution. Consider Madison, Wisconsin, where all the signers of the Constitution (save one) have streets named after them. And who's the exception? James Madison.

I used to win a lot of bar bets with this information, back when I was a student at the University of Wisconsin.
