We've hunted out of "The Blynd" blinds (3 of them) for years. Eventually with the wind in Texas, they begin to come a part a bit. The one below is my wifes at our ranch. I will be replacing it with another one in better condition on the 5' tower like yours during my trip in a few weeks.
I now hunt form this one, The Sportsmans Condo. It is a 4'X6' single piece of thick plastic. It seals up better than the Blynd, less noise, more costly, more weight, but so far I prefer it. I am about to buy another one in a 4X4 to attach to a trailer I can tow out to my new hunting spots.
