I would hunt just off a food source if possible. This late in the season the deer are gonna be getting ready for the winter. If you sit just outside of a field then you can maximize the area you can see and have the possibility of catching something coming from its bed to get some food before sundown. If hunting in morning I'd go farther in from the field becuase you don't want to spook the deer that are already feeding in field in the morning when you go in.
