RE: Locking Your Stand
I had a stand stolen from me a few years ago. Whoever stole it, cut the cable that I had securing it around the tree.
To top it all off, it was on private property!
The only SAFE way to leave your stand is not leave it in the first place. If you are going to be hunting in a stand on public land, either build one (if it's legal in your state to do so), or use a climber.
You can't trust anyone these days.
