Well it happened to me this september. A 21inch nine pointer chased me outta my grandpas hayfield two weeks before season, how do i know it was 21 inches you ask? because i shot him the second day of season. This was the most territorial deer ive ever seen. I tried the standing your ground thing i was kneeling at first then stood straight up and yelled GET OUTTA HERE and he kept coming so i pulled my pocketknife out as a last course of action, he then charged and stopped at about 5 feet by then i had thought of everything thing i could imagine, how i was gonna fight him and everything i figured i cpould put my arms out to try adn get a hold on his horns but i had backed up close enough ot the fence then i turned and jumped into the woods, I got soem trees between us and slid down teh holler and he let up some then he came to the edge of the fence and made sure i was leaving. I dont think he woulda done anythign physical unless i woudla retaliated or acted dominant towards him he just wanted me gone. After i killed that buck i knew there was no way i woudla had a chacne fighting a mature deer like that he woulda killed me in a second.
