Little story.
Buddy of mine and myself were riding through one of our clear cuts when we were about 16-17 and I'm looking out the window. All of a sudden I see one eye, one ear, and half of a rack in the thicket. I tell him, he calls bs, so he stops and backs up. I'm pointing at the deer and he finally sees it (maybe 15 yards), it didn't run until we opened the door. Looked like a freak rack deer with points everywhere. My brother ended up killing the deer during season, it was a messed up 10 point. They will let you go right by them. On a side note, I've had deer "drop" at the sound of a shot in a clear cut and lay there. It's happend twice to me and I know for a fact the deer wasn't hit.
