I cant count the number of deer Ive shot while kneeling on the ground. Most with a 70" longbow, or 58" recurve. The key is; practice how in ways you might have to hunt. Opening day, I wont be hunting my land rather a good friends. Ill be on the ground the whole time. Mostly spot and stalk. When I get set, ill be in either a makes shift ground blind, or kneeling by a tree. Shot two deer on his land last season while kneeling in an open field, behind some tall grass, shooting an Osage selfbow 70" ntn.
