RE: Treestand tip for those with lower back pain....
I wear a neoprene(I think) back support while stand hunting. It wraps around my waist and then it has 2 straps that start in the middle of the back and you stretch those toward the front to give some more support. It resembles the back braces you see people that deliver a lot of goods(soda truck drivers, ups, etc.) without the shoulder straps.
