I got a $10 bill in Green Bay with a note to go to www.wheresgeorge.com. If you have a bill you enter information about the bill and where you got it and then it shows you where the bill has been reported. One of the bills has been reported 15 times in the past two years and has been all over the place. Very fascinating. My bill was first reported in Appleton, Wisconsin the day before I acquired it. Statistics are kept for the bill (miles traveled, average traveling speed, etc...).
