>Somewhere there's a joke about "burn-a-debt'" (let's see how good your memory is) and the $100, but I can't quite figure it out.

Oh yeah, good ol' "burn-a-debt"! I remember her! Don't know what joke you're referring to though.

>I thought most people rarely carried cash around - guess I was wrong...only a small # said they didn't carry much of any cash.

I only carry the little bit of cash I do for the times I go grab a quick bite at lunch-time or happen to go to Starbucks or some other coffee place. Neither of which happens very often lately (used to be a lot more when I had money!!)
