So, if I stand on the edge of public land, stretch out my arm, wave it around above the private land, I'm trespassing? I suppose I'm willing to be that criminal that will step over the corner pin, not setting foot on the private ground, and do my hunting.
If I were a real jackass of a property owner, I'd only need about 20' of fence and six posts, and just fence an 'x' at the corner. This comes down to a simple GMAB, but both hunters and landowners have been and will continue to be jerks on this count. Sometimes just pure greed, but other landowners have had their property trashed by jerks calling themselves hunters, and one can understand their POV. But the lands are public, and landowners should not be allowed to lock up public lands by preventing corner crossing.
Probably didn't add anything, but there it is....
