RE: When to remove a lock on that is...
I didn't agree with it, but he is a grown man and makes his own decisions. He had rationalized it by saying the landowner hosting us would be happy with his decision and want us to take that action. I still thought he should have just left well enough alone. Years ago I had a lock on taken from me. I remembered being all pumped up to conveniently go jump in it for a morning hunt only to find it had been stolen.
Still, I wouldn't feel just in taking down a stand that didn't have anything to do with me. Why would I bother?
I do agree if it is on private property then there is a case for taking it down.
