The last few years I have sat in a 5x5 ground blind overlooking an ag field along a creek. There have been several deer, and coyotes killed from that blind. Generally the blind is set up from late August till January. Have had some of the younger deer actually bump the tie down cords. Last year in December rifle season a buck was killed about 20 yards from the blind and in Sept. muzzleloader season a doe about 30 yards out.
I have had 2 adults and a 7 yr old and that gets a little tight. I set up 1 swivel chair and keep a bag chair in the corner for a 2nd person.
