I've built around 10 4X4 box blinds, out of white pine, have hinged shooting window cover to discourage yellowjackets and wasps, just close up the windows thru the warm weather, build them in a garage, upset them onto a tilting trailer, pull them to location with my terry-x, stand them up and level them, will try to get some pics Monday got 2 almost complete in the shop.
