I have studied deer for over 40 years. When I hunt them I know exactly why and what kind of trail and tactic I'm going to use. I hunt food at certain times of the year and I hunt cover at certain times of the year. It all depends on what I'm after. In the grand scheme of things, in the most general sense, It's always about food and cover. A lot of times evenings = food and mornings = cover. BTW, where I hunt food is where ever the deer is standing. Everything is food to them. They just happen to prefer one over the other or the other over the one. That's for you to figure out![:-]
