i feel that game, really of whatever species, can be hard enough to find, stalk and/or kill in the first place. How are you suppose to kill deer? if they have no reason for coming into your tree stand area, then they simply wont. The only way i see it possible if you were to hunt on the trail between a food source and bedding area, and even that can be tricky. Or you can stalk hunt. I feel that it is perfectly fine to use feeder. That is one of my favorite parts of hunting, locating good spots for stands, feeders, shooting lanes, etc, in an attempt to produce large deer herds (and large deer) when the season comes. I dont only think about deer when im hunting, im always thinking of new ways to make the next season better. You are already using camo, scent blocker, etc, what does a food source matter? by ur co-workers methods, he should sit in a tree stand with regular clothes and not use any scent blocker. It all goes with hunting IMO. just my thoughts.
