Just by your walking through the woods wont bother the deer ,not unless you did it everyday . Even then they wont leave the woods ,just change thier habits and adjust to your being there . Have you ever seen all the deer that live in big cities and are around people everyday. They learn to adjust more than you think . I think the biggest thing that affects hunting is when everyone suddenly goes to the woods on the week just before the start of the season and the deer don' t have time to get used to all the extra traffic . They go nocturnal in a flash .
