Any time you can hunt is the best time to hunt
Like already said, I would hunt aways off from food sources. Stay back into the cover a little, where they might stage up before heading into the feed at dark. Look for good trails, and then place your stands near them. A trophy buck can walk by anytime, but you'll never know unless your in your stand. The only downside to early hunting to me is the warm weather. I prefer to let my deer age for at least a week. And that is hard to do when it's in the 70's.
