I leave six Summit’s in the woods at my club during the season (I pull them after the season is over). All are cable locked to trees, but they are also in areas that are a long way from club boundaries. I also make sure they are angled so water doesn’t flow into the tubes when they are locked to the tree. Last, I don’t leave seats on them. The seat I use attaches in about 30 seconds. Easy. So no wet arse for me.
