Excellent point.

Shows how paranoid I am - when I make a withdrawal I do it from the ATM outside and make it pay out $100 bill denominations. I then take the bills inside where they exchange them for me (without showing ID).

Not impossible to track but the broken chain makes it harder.

My bank's ATM deals only in $20 bills.
