I haven't found anything really strange, but I have found some stuff...
Random tools like a tack hammer, pliers, etc. far from any road. A stand of marijuana plants. A rotting dirt bike. Various car parts. Rusted, shot up farm implements (old plows and such). A memorial to someone (picture in a tree hollow with a couple personal effects and a soggy envelope with a letter in it). A shrine to the Virgin Mary (statue in a tree hollow with a few candles).
It's always funny to stumble across the remains of obvious juvenile delinquency in its more innocent forms, like a pack of cigarettes stashed in a tree, old Playboys and such stashed somewhere, etc. It's not so funny when they're more grown up and it's beercans, broken bottles, and other trash.
Now a Stihl chainsaw, that'd be cool!
20 rotting deer in a trailer? Not so much... I can just imagine the smell...
