It's funny -- I was a scout once myself, back in the '80s, and one of the Scoutmasters was a big-time MDer. I remember going to summer camp, and he'd clean up: I'd see him spend a few hours with his screwdriver digging around under tent platforms, and he'd come back with a SACK full of old silvers; SLQs were a dime a dozen back then.
I haven't hit any scout camps myself, but I keep hoping that spots like that still exist. Keep digging!
Cheers and HH,
