I was out for lunch yesterday and paid cash for my Quizno's sandwich.... I usually pay by debit card but this time I actually had a $20 bill in my wallet. I pocketed my change, ate my lunch and went back to work. when I got home and dumped the contents of my pocket on the dresser, I noticed some hand writing on the $5 bill I received as change at lunchtime, a closer look revealed "where have I been .com". Of course I looked it up and sure enough, there is a website dedicated to tracking where various Canadian and US currency bills end up. I though it was pretty interesting and I will put my own into circulation to see where they end up.... kind of a new spin on the old "let a balloon go and see where it ends up".... anyways, if you are interested, here's the link - http://www.whib.ca/
