Re: most amount of $ you've found and where?
I remember walking home with a friend in like...maybe 5th or 6th grade and kicking a pile of leaves and a dollar popping out. We did that slow motion look at each other and both dove for the pile and ended up finding 11 dollars or so, can't remember. We split it and got chocolate wasted at a convenience store.
Other than that, I did find $80 in a pair of jeans a few months ago that surprised me. I didn't remember missing it or losing it. I don't remember what I did with it either, probably back to the bank.
