They will come back, in the right conditions. Where I hunt, I am fortunate enought to have a silage (spelling?) pile 15 yards away from my shack, so when there is a fair amount of snow on the ground, the deer come in pretty thick, we have shot 4 in one afternoon before, we took 2 fat does with a bow, and 2 more with a ML. we left em lay out in the snow not even 5 feet from the pile after we gutted them, which we gutted them right where they fell, and that was only 10-20 yards away. They just kept coming in like ants to a picnic. And thats an every day thing, I bet we shot 10 deer there in a month, and it didn't stop em.
