We seem to be heading for the British solution, where the game belongs to the landowner and there is no 'public' hunting.
As long as gun ownership in America is a right and the game belongs to the public, there will be people abusing someone else's private land. Just as there are people abusing by illegally posting public land. And - more and more, these days - non-resident landowners buying up and locking up game habitat.

The long alliance between hunters and farmers is all but over. Unposted land is now the exception, leasing and posting the rule, and game has become a cash crop.

The fundamental problem - for hunters, and for everyone else on earth - is that there are more and more people grabbing for fewer and fewer resources. In a remarkable achievement of PC sleight-of-hand, everyone's babbling about 'controlling' global warming, and no one dares mention the real problem: overpopulation.
