If there is a road then you are ok. You just have to stay on the roads/trails. That doesn't include the trails that other people make just for the heck of it.
Although people around where I hunt drive all over the place and they are not supposed to. I would get one of them ther deer carts. That is what I am going to do after having to drag my doe 600 yards in all that tall grass and brush. Talk about a workout.
