Hey jb,
Don’t take it personal that you didn’t get replies to this. I am one of the viewers and thought that it was interesting. It would be more appealing to me, if I had an expanse of private land to construct a few of these. This way, you could take your pick and hunt according to the wind direction.
Many of todays hunters are faced with hunting public land, and a permanent ground blind is considered public property, therefore (like myself), portable blinds are what a lot of us are using.
