I don't know about ladder stands; they would be a hassle to take down and put up over and over, so I've never used them. However, we do leave loc-ons up on private land all season. I have had several stands go missing, though, so I've taken to putting a strong chain and padlock around the stand, just like a chain-on type locking mechanism, if I'm leaving the stand in place. I really prefer to use screw-in steps and a light, easily attatchable loc-on stand that I take with me. The set-up is in place; all I have to do is climb the steps and strap the stand. I'll have a small nail or something to hang the stand on so I can free both hands for securing the strap, and so the stand goes back in exactly the same place on the tree when I take it down. Screw in steps are fairly cheap in bulk, so if someone takes those I'm not out too much, but stands are expensive.
