Took me awhile to read this entire post and I'm quite sure I've probably missed some points! That's a helluva lot to digest! !I think there are plenty of people who would be willing to allow friends and neighbors to hunt on their land, but have been burned by open gates, rutted fields, friends bringing friends of friends, etc those are the people no matter where they hunt public or private are going to be bad stewards of the land. Unfortunately, we can’t bar them from using public land.
I actually see only one drawback over this issue.
If you happen to be hunting public land and decide to cross over onto private property where you have permission to hunt, what's to stop the poor schmuck behind the tree to your left from thinking. "Hmm...! He crossed that fence! Must be public land!"
Even if my chances are better on public land, I'll hunt private ground instead. It's not the kill that counts, it's the experience afield. I don't want "Bubba Gump" moving in on my hunt*. A "kill" is just icing on the cake.
I see no problem with a private land hunter taking advantage of public land.
I have NO qualms about a land holder restricting access to his/her property.
* - if "John Dumb" sees the birds I'm working, he has every right, morals and ethics aside, on public land, to set up on the same set of birds and begin working them.
