For years I used to walk alot because my family didn't have a car...

$10 bills here and there...always look at empty ciggarette containers.
A $50 bill...that was at college and I was hard up for cash. So that weekend started on an upnote.
A couple of $20 bills...rare...
Some Nokia phone...let it dry out and it worked.
A camera...one of those autofocus w zooms, not an SLR or anything.
A couple of CD's...some worked, some didn't.
A half full dime bag...but the herb was moldy and there was road dirt in it.
Needles...needles...needles.....lovely NY and North NJ...
A calculator...meh...
Someones 'wedding night' video...The tape was on the side of the road and alot of the tape was outside of the actual cassette. What I could salvage turned out to be a homemade porn video. I don't know if it was really their wedding night. But the tape was so degraded and it was of very little interest.
Other little odds and ends...nothing of great value, maybe aside from the camera. It was a good one.
