I live in N.H. and where I hunt is semi open with thick patch's. I was sitting in the crook of 3 trees one morning and had a 4 pt run right up to me. He was so close his breath was hitting my face! We were like that for about 1 minute and I wasn't going to take him 1st day of blackpowder. I said Hi there, he went vertical with full afterburners, I guess he never had a tree talk to him before lol.
The actual closest shot was about 35 yards, most of my shots are 50+ and usually on running deer. I just pick my window through the trees and wait for the deer to get there. I have about a 90% success rate for 1 shot 1 deer every year for the last 30. I have only shot 2 deer standing still, that's what hunting in N.H. is usually like, with all the tight rolling hills and thick woods, twigs and leaves, its hard to sneak up on a deer. As far as waiting for one to come by, with 1 deer per square mile where I live you may wait a long time.
