i haven't hunted out of a ground blind since i don't know when, in south texas elevated blinds are much more common place, and when i'm hunting anywhere else its usually in a truck or on foot.

i did shoot my first two deer out of ground blinds, one was abandonded for god knows how long, but the trail that 50 yards in front of it was still well used!

i don't think it makes a difference, a blind is a blind. i think it all depends on location. some places are very well suited to ground blinds
