This is my first year trying a blind. I went for a Rhino BC150 because it has clips on the doors and hooks on the windows. No zippers and no Velcro. On youth weekend my daughter got her first deer(5 pt). She had time to get her earmuffs on, get behind the rifle(tripod mounted) and aim , neither deer knew we were here. Now this morning she’s a little tired so she’s covered up with a blanket on the floor (laid a moving blanket down as a floor) and is resting till the deer show up.
