When hunting back east on State Game land, I look for funnels and really in most states where I hunt whitetails. I normally hunt in tree stands in thick stuff. Snow really helps, if I can get it. When hunting pressure starts, bucks stay in cover. I normally don't hunt food sources or open areas back there, but that is in PA and in the mountains, where acorns and local grasses are the primary food source and could be anywhere. I really hunt off of hunting pressure. Texas is the exception. When hunting in Texas, the corn feeders make it relatively easy in some ways. When I hunted there I normally glass down wind from the feeders, when does are under it eating. I found bigger bucks hung back. Fields on the lease were also productive early and late. A lot of variables, depending on state, laws, public or private land, etc. Thats the fun of it. Strategery.
