With ladder stands, I use ratchet straps to secure them to the tree. At the end of the season, I release all the pressure from the ratchet strap so it is hanging loose. I tip the top of the stand a way from the tree a couple inches and set it back down against the tree. The loose strap is enough to keep it from falling off the tree with no weight in the stand. This keeps the tree from growing around the metal and allows the stand to move freely as the tree blows in the wind.
Next season, I'll inspect both the strap and stand welds and replace the strap if necessary.
I keep my climbers in a small Rubbermaid shed next to my garage. Keeps them out of the elements but they don't pick up odors from the house, barn, or garage.
Thanks,
Jack
