Should a farmer have the right to exclude hunters from his land?
Most States insist that property be properly posted in order to exclude hunters/trespassers.
Naturally, if a property owner sees you on his unposted land, he can request that you leave.
-- Although some States allow 'fair recovery' of game shot on one property - that dies on another.
And if he says, "You're welcome to come back if you leave your gun at home"
Second amendment violation?
