I had my chance one morning while in my blind. It was still early. I didn't know if it was a buck or doe till it got close enough. It was maybe 10ft in front of me, and it was a small buck. I could have shot before it was in front but didn't, too early. Then it too off. Think it was 640-645. It was cool it was that close, didn't smell me. Think chair spooked it.
