Now that I think about it, unless I use a really thick chain it won't be any better than a 5/16" cable lock - right?
You are correct if you are talking about regular bolt cutters. The heavier cable locks are difficult and time consuming to cut with regular bolt cutters. But, a cable cutter goes through them easily. Bottom line, if somebody wants your stand bad enough, there is very little you can do to keep them from taking it.
The best system I have seen for getting around that problem a little bit are the stands that fit onto a bracket on the tree. It allows the placement of the stand, trimming shooting lanes, etc. Then you can leave with your stand and climbing sticks with the bracket left up in the tree. An extra bracket for insurance and you should be good to go when you return. Yes, it adds a little time to getting set up when you return, but you don't have to worry aout your stand being gone, either.
