Went to see Hero this evening (short review: state of the art hack and slash, worth seeing) and got a dollar bill back in the change that had been stamped with a message saying “Track My Journey Across The U.S.A! Please Enter My Serial Number At www.wheresgeorge.com”
Went to Where’s George and discovered that the bill had initially been marked in Barstow, travelled to Hawaii, and then worked it’s way back to Irvine. Kind of a cool site for triviaspotter types like myself. I’ll let loose a bunch of these on the trip east.
