Over a year ago I got interested in the web site Where's George which tracks the travel of US paper money. Basically, you enter the serial number of one of your $1, $5, $10 or $20 bills and then optionally write the URL of Where's George on the bill. Hopefully someone that gets the bill will see the note on Where's George, go to the web site, and log that they found the bill. I must have entered about 20 bills into the site, hoping to see where my bills wind up.
I didn't receive any notifications until 3 days ago. It turns out that one of my $20 bills has been found and logged. Guess where it wound up after over a year? Santa Monica, CA - about 4 miles away! Not very far, huh. Here is the log for that $20.
The Where's George idea kind of reminds me of a children's show I saw in grade school in which a child receives a $1 bill from his dad and spends it on candy or something. Then the show follows the path of the bill to various people. It changes hands throughout the day until the evening when it happens to land right back in the hands of the child. I think there was a mark of some kind on the bill, so the child realized that he received his same bill again. Anyway, I'm not sure what the point of the show was. It probably was trying to expose children to the different jobs and activities that people engage in every day in a typical American town.
