The last one I put up by myself, I thought I had it tied off pretty well that I could climb up and get straps on it. I was wrong. It's a giant oak, when I got to the top, one thing lead to another, it started to give way, and I grabbed onto a big oak limb. I tried to pull it back with my legs, but that was just a dumb desperate attempt. The thing slid away from the tree tied well enough that it didn't hit the ground, but I ended stuck in the top of that tree standing on a limb for a while.
Called for help, my wife came and saved the day. Took a while talking her through getting ropes and pullies so she could get it stood back up. I tied it off from the branch, and decided that putting up ladder stands solo just isn't worth the risk.
