How long does it take for you guys before you think you have a new area figured out for hunting whitetails?

For myself, I am speaking about farm land. I like to get 2 crop rotations under my belt before I think that I have a grasp on things. This means 4 seasons for me. Granted, things get easier as each season passes, but for me I like to start seeing a pattern.

Certain things can change from year to year but crops can and do affect a deers behavior and habbits. I have a stand in a fence row that tees into a steep ravine. Each side of the fence row is rotated with corn and beans. The fence row runs north and south. During the seasons when the corn is on the east side of the fence row there is better deer activity. That one I can't figure out.

After 4 seasons I start to know what to expect. I know where the does prefer to bed and where the bucks like to bed. You get to know what foods they prefer at different times of the year. Once you know these things it helps when planning your setups.

Other things I watch for are blowdowns and beaver dams. These will alter deer movement. I had a dynamite creek crossing go dead because of a beaver dam, The deer moved down stream to an easier place to cross. I've also sawed apart some blow downs in order to keep the deer movement going past my stand instead of around it.

What are some of your experiences??
