I have a 150 acre parcel, mostly woods and some fields. I kept it open for many years because most people were mostly respectful. Last couple of years I've had way too many yahoos leaving beer cans all over, dead deer carcass's (probably poached) and even a giant ugly couch. Now my driveway is gated and locked and I've had to put up no trespassing signs. At some point it's just not worth it. Too many people abusing the land.
