I bought a quick dinner snack in a hole-in-the-wall Indian called The Pakistani Tea House this evening. New York isn't famous for its curry, but this place wasn't too bad. The naan was cooked in the tandoor in front of my eyes, and they had the decency to put the food from the big tray in the microwave before they gave it to me.
And for $6 it was damned tasty.
Amongst my change, I noticed one of the bills had a message stamped on it: "Track this bill at www.WheresGeorge.com". This jogged my memory about the website it mentioned - I'd read about it a couple of years ago. It allows users to track where US currency "travels" by relying on curious citizens going to the website and entering the relevant details.
So I did: http://www.wheresgeorge.com/report.php?key=0fd955b752c8d131f4eaee10a0253e16bf442c8f10e1ea82
It'll be interesting to see where it ends up.
