This replaced a rickety old box stand on stilts. The sides were just linoleum or whatever stapled on. If you dared lean against them you go right out the side. I froze in that stand for many years. There was no reason for it. It was only ten feet up and this is the top of a high hill. I see just as well as I used to. And the deer are used to it now. It's been up two years. Squirrels haven't bothered it either. It's 1/2" treated marine plywood. Carpeted floor also.
Btw, no bucks. The season is over for me.
