Has anyone ever used one of these style blinds? I'm wondering if I can "box" round a tree with my back to the tree and hunt like that. I guess I've been used to hunting out of a box stand and I can move around and not have to worry so much. Now that I will be hunting on the ground or a small treestand in the woods, I'm trying to think of ways that would allow me to move a little and not get busted.
