I have had the regular blynd for 30 years. I have rotted out a couple of floors but the blynd still is holding up strong. I put 2 of the 4x4 blynds together when my kids started hunting with me and framed the sections so it would be easier for one person to take down and move. It has been a great blynd and I have raised 3 kids in it.
I just built me a new deer stand and gave mine to my kids so no telling how long that stand will be around.
I once drank muddy water out of a hoof print and was dang glad to get it.
