I would look for any possible fencelines along the creek and find areas where the fence is down or partially down near a shallow area of the creek where they would cross. It is hard without a topo but I like the shortest distance between feeding areas where there is water nearby.

There darker grouping of trees north of the orchard, are they oaks? If they are oaks you will also have the liklihood of deer traveling from the orchard to them as part of their travel path as long as there is a good acorn crop.

I would also walk though the woods along any deer trails and look up, chances are someone hunted it in the past and already has an area marked for you.
