The closest I ever got to a buck on the ground was about 8 feet. It was in the parking lot of a place I used to work at. I got off work about 10pm. I walked out to the lot and saw a deer down in the trees beside some cars. With the wind blowing hard from the buck to me I started sneaking down behind the cars. I got to the last one and when the buck lowered his head I stood up beside the last car between us. I stood perfectly still against the car. The buck was so close I could hear him chewing the acorns he was eating. He was a nice 2.5 year old 8 point.
