Where's George?

I got one of those marked dollar bills that has been tracked as it travels across the US. This is what the website says:

One Dollar Bill, Serial# B7234---9J Series: 2003A



This bill has travelled 687 Miles in 2 Yrs, 135 Days, 1 Hr, 19 Mins at an average of 0.79 Miles per day.


It is now 657 Miles from its starting location.
