The only time I've ever used one was in the middle of an extremely large open field with no cover. I usually dont like a blind if I can help it cause I want to be mobile if I need to but in this case, the bird would fly into the middle of a 100acre wheat field with his hens every morning and after the 3rd day, I got tired of it and grabbed my blind (I deer hunt out of it every once in a while) and ended up killing him. They never noticed it...
