A ground blind can be anything you want it to be, be creative. I own pop-ups, but I'm just as likely to use my surroundings and natural materials. One winter morning I sat on a folding stool withthe military issue snow camo poncho I was wearing draped over it. Many deer came well within shooting range that day and never noticed me. Another favorite tactic for me is tosit ina low spot such as the hole made by a tree's rootball after a property has been logged, all it takes is seat and some camo, deer never expect a threat from below. Log piles on the same type of ground are also excellent cover.
