The above post is why, IMO, permanent tree stands should not be allowed on public land, and a portable left in place is a permanent. That's the way it is here in NY.
A couple years ago, I got a permit to hunt a nature preserve. They allow deer hunting so that the deer don't overeat the place, which they do, of course, if left unchecked. The only rule they had regarding tree stands was that you could not use a stand which punctured the bark. Well, upon scouting the area, there were more ladder stands in all those good spots than you could shake a stick at. I would have continued hunting there if the state land rule applied.
