Where's George?

As part of our study of money for the composition this week we are conducting an experiment to see how far and fast money travels. Each student was given a specially marked dollar bill, the serial number of which I have entered onto a website that tracks the travel of currency. Our hope is that after spending the money, a kind soul will receive it and log onto the website and put the serial number in. The website is http://www.wheresgeorge.com/. Obviously no student names are used in any part of this experiment. There is an 11 percent chance that a bill will be entered into the website after its initial posting and the average wait is 29 days. I will be sure to report if any of our bills are entered. Here is a picture of the bills all together. Who knows how far they will go from here?
