I have 3 blinds 2 I set up sept.1st and leave them in my hunting spots all season,the 3rd blind I keep at home for when I want to hunt public ground up the river.I have killed 3 deer out of this blind and all 3 times the deer was within 10 yards of the blind they looked at the blind but cant see me because all my blinds have the mesh windows,so in my opinion they notice them but it doesnt scare them unless they wind you.
