I started doing this sometimes this past season. Getting old and knees are shot. I picked up the upper half of an "Ol' Man" Vision climber at a yard sale for $5.00. Bottom was busted. Probably weighs 8# or so. Hung on a tree, it makes a decent "chair" . If I conceal myself, I use brush. I try to set-up on a ridge. I'd rather be off the ground but this works OK when there is a definite and steady wind direction.
