ANY deer that makes it past 2-1/2 gets harder to get close to on a majority of hunts. Certain things can and do happen that make exceptions to this rule, but a deer that has had a close encounter very rarely makes that mistake again. Does that are "easy" to kill have either not had any hunting pressure, or are really really used to humans being close by. I'm more worried about being busted by a doe any day. Mature does are some of the most cautious creatures there are!
p.s. Joe - That is the magic of editing and those TV hunters are hunting racks, mostly off managed property where they have the opportunity to pick and choose because the ranch or property manager or guide (whatever) is helping to let those animals grow to full potential, so there's kind of a minimum score limit. It makes for good TV and plays the hunter out as some kind of hero. Kinda like watching NASCAR for the wrecks.
