I've always liked that story Dan Infalt tells about driving a decoy car with PETA stickers and "I Brake For Raccoons" stickers when he was scouting a spot. That said, I've got stickers on my truck for a handful of organizations I support. Bottom line, you live in a place rural and small and folks know who the killers are. They know the trucks and cars whether there's stickers or not, and they drive around the county and see where folks are parked. They'll say, "I saw so-and-so's truck parked over off Flat Creek." Don't matter. You just have to have plenty of spots. Plan A ain't good enough. You need the whole alphabet. Outwork the lazy slobs.
