Several days ago, I got a one dollar bill, which had a strange message - “Where have I been? Where will I go?”. In addition to that, “TRACK THIS BILL WHERESGEORGE.COM”.
Seems the site is tracking individual one dollar bills by the number of them. According to Wikipedia, this interesting social experiment has been running since 1998.
I entered the number of my bill to the site. So I will use this bill soon, to see what’s going on.
