RE: How many do it??
It's funny you mention this, as a I was going to start a similar thread concerning climbers vs hang-ons. I scout a decent amount to get an idea of where I want to place the stand when I enter the woods, and I will sometimes move a climber from one spot to another and hunt it the same day. I've never shot a deer the same day as the move, but I've definitely seen deer due to the switch.
Now, not trying to hijack the thread, but to add into what Vabow is asking...those of you who use climbers, how many of you leave them in the woods? Or do you take them off the tree every night/morning after the hunt?
