During gun season, I hunt with a club that uses deer dogs. The dogs are released into known bedding areas. We hit the same areas sometimes twice a week and there are always deer there. Once the coast is clear, the deer will return. One spot that we run is a patch of woods, mostly oaks and pines, and briers galore, about 100 yards wide and about 500 yards long. This patch lies between two agricultural fields. After driving dogs through this strip of cover and jumping deer, I have seen deer come out and graze in the fields less than an hour after the drive was over. Some extremely thick areas that we hunt, the deer will not leave the area. They will run around in the area all day and will not come out no matter how many dogs you put in there.
I'm convinced that deer will use the same bedding areas regardless if they are disturbed. Once the danger is gone, they come back.
