I've probably killed as many off the ground as anything. I do own a pop up blind but never liked it much so don't realy use it.

My first buck was shot with a bow on the ground at 20 feet. He wasn't huge but man what a hunt. I had camo on but wasn't in a blind but did have a good background. The deer never saw me walked straight in with his nose to the ground. I thought I'd have to shoot him in between the shoulder blades (new bowhunter thought. I'd never take that shot) He turned broadside at 20 feet and the arrow passed through him before he knew anything. He jumped a log and stopped to look back at me. Then took off and ran a big arc. He ended up running into a tree and staggered a few more steps and fell over. Died on he feet.

(My bow was a mid 70's bear polar 2 compound)

On the ground close up is an awesome hunt. You have to do everything right.
