I prefer my treestands to be about 15' off the ground, but I've also hunted from the ground, 3' off the ground while standing on a stump, and as high as 32' off the ground.
What works best for you and do you really get any more of an advantage for being 20', 25', or 30' off the ground?
PS. I missed one while standing on the stump but got one while just 8' up and at only 7 yards.
From those who much is given, much is expected
