Help Where's George? track the geographic movement of U.S. dollar bills. Participants enter the denomination, series, and serial number of any U.S. dollar bill and their current U.S. ZIP code or Canadian Post Code and they can see where the bill has been if it has been entered before and see where it goes if it is entered again. The project is only for fun and does not track participants' personal information. Participants do not have to register unless they want to see where a bill they've entered goes next. Although the project is for fun, it is generating useful scientific knowledge: mathematical models derived from the project are also being used to show the geographic spread of infectious disease.
