What's the point? -- Ever stare at a dollar bill and wonder where it's been? This Web site gives you answers. You can plug in the serial number of a bill, the year it was made and the series and you might find at least one other person who's had it in his or her wallet.
What to look for --The previous location of the bill. We picked up a $1 bill someone had in Lewisville, Texas. Somehow, in the past year, it made it all the way to Baltimore. The site calculates how many miles the bills travel from point to point.
