Wheresgeorge tracks members bills though, those would mostly be carried by people going from one state to the other, not through Federal Reserve branches right?
Since most places you pay cash at take it straight to the bank ASAP for security reasons, most of your cash ends up at a bank. In fact, I'm having a hard time thinking of a business other than maybe a hotdog stand that doesn't take 100% of their cash revenues to the bank.
