Guess it depends on what you mean by 'blind.' To me, it either means one of the TENTS that are currently popular, or what has been referred to as a 'natural blind,' i.e. a blow down or the like that is hunted as-is, or perhaps has been modified a bit. Personally, I don't use the tents, but the biggest deer I ever harvested (9 point) was from a natural blind. I've also taken a few from no blind at all.
