I saw a huntin show this week were a guy was huntin from inside a hay bale blind. I was thinking of getting some and making a few myself. I was going to use the rectangle bales. Was thinking of arranging them where I would have three walls witha window, (hole) in each wall and also put a board on top to keep rain and whatever out. Anyone ever done or do this?????How does it work out???? Any suggestions on size andbest pattern to build it???? Thanks, Scott Woody
