Ive hunted a ton on the ground. just make sure you are tucked in enough that you dont stand out too much. have good camo possibly a leafy suit. and MAKE SURE you can move enough to get your bow around and drawn back without being to noticeable.
I killed one a couple years back from about 5-6 yards off of the ground. the deer pretty much ran up on me, scared me tbh. i drew back and smoked her.
