disc thieves. I have only been playing two months and I have retrieved and returned 20 disc from some nasty terrain; briar patches, skank water, 80 foot trees. I have even made effort to return disc with no name or number. I lost my first bought disc in a water hazard but was in a hurry so I didn't snag it, just knew someone would call. nope
that doesnt mean its stolen, that means its lost and you didnt retrieve it.
