I use hardened 3/8 chain on one of my large stands that is close to a WMA. With the lock and chain secured similar to what timber is saying it would take ladder and a torch to cut thru everthing. If they got thru all that it would take two men and boy to haul it out. Moral of story is don't put cheap chain and lock on. Think like a thief and then make it harder than its worth to steal.

My bro in law built a 18-20' stand only to find out he couldn't see didlee squat due to branches etc. For the area he built stand (alot of Hollys) a 10 -12' stand would have been perfect after a little trimming.
