I have recently sat in just such a blind. It had an office chair that would swivel 360. Comfortable. The only problem: I would have liked for it to have been better situated; I might have then bagged a deer for my freezers.
The "Rack Trap" ... I've seen a few with different types of wiring to catch the antlers. These look like elastic bands which (I'd like to think) that if the antlers weren't ready to drop the buck wouldn't get tangled. What do you all think?
