I've killed dozens of turkey, and have never found the need for a blind. I don't even camo up, I've called birds to within reach wearing nothing but my street clothes, even a red plad flannel shirt. As long as you aren't moving or making noise, they'll never know your there.
One of my Son's just bought this elaborate blind yesterday and I'm trying to find a gentle way of telling him I won't use it for turkey. It would be nice for other hunting activities, but not turkey. When I'm approaching the roost area in the pitch black of early morning, where I put the birds to bed the night before, I want to do it with the least amount of movement and noise. Decoys are nice, but not blinds.
