Where are they bedding? they will use the wind to and from the bedding area. How much browse and food do they have to eat in the timber? This time of year, deer don't really have to move to eat, they just browse more for social behavior. By the wind direction, they will usually favor one trail over another, find it with the changing winds and block one trail. I found out long ago, don't just hunt one trail. Find and intersection of a few trails, this obviously increases your odds. Keep a log of wind, temp, weather, food and action as well as time of day, in no time you will see a pattern emerge. I Like to use some thing I learned from the Wensels books, set up a stand a distance away and pattern the animal's without disturbing them, then move closer, then you will have them narrowed down. hope this helps.
