Purchased 2 penthouse blinds with 10' towers for elk hunting/guiding in Montana. They are a game changer, they mask your scent great. We set them up in high traffic, rutting areas on the ranch and the elk did not even hesitate to pass right by them. One morning I had a herd bull with 30 cows come right to the blind and they all bedded within 30 yards on all sides of the blind. Going to purchase another one this year.
