http://www.wheresgeorge.com/]Wheresgeorge.com[/url] is a cool site I found where you can enter a dollar bill's serial number and where you are, so that if anyone goes on and wants to know where their dollar bill has been, they can check (or vice versa). I decided to enter every single bill I get from now on and then write "Wheresgeorge.com" on the bill, that way the people who get it after me can see it's history. The site tells you how many bills you're entered and how much money you're collectively entered, and it lets you add a little note about where you got it (and/or it's condition), so that the people after you can see where you got it from. I will also be writing where I got each bill.
