Last few weeks in Feb. are the time to go scout. The woods are waaaay more open in that time than the summer before season comes in. You should still be able to see buck sign and can go walk the thick areas without being worried of pushing the deer out.

How you hunt needs to determine what you look for when you scout. If you plan to bowhunt then scout for the trees/food sources deer will be using at that time. If you plan to gun hunt I would look for terrain features and pinch points as mentioned. If you are scouting WMA's I'd focus on a tract of woods that has plenty of distance between the roads of possible. The harder a place is to get in, the better it usually is. Scout the other hunters as much if not more than the deer themselves..
