I once stalked a 2.5 year old 9 point to within 4 feet, his face to mine. It was at a place I once worked. The buck was eating acorns on the sidewalk in the parking lot. The wind was perfect. When he put his head down, I would take a few steps with vehicles between us. I finally got to the hood of a little blazer and the buck was right beside it. I ended up leaning on the hood. He picked his head up to chew and was within about 4 feet of my face. I could hear him chewing! I never blinked and he never saw me. Eventually he meandered away. There was a massive buck there too that I could never get close to no matter what.

That deer in the pic is undoubtedly a Button Buck, they are so stupid. That is why Atlasman and aka/Deaddeer et al hunt them exclusively! Hehehe
Just funnin' now, season's commin soon.
