Get him started early well before the season starts and it wont effect your hunting very much. Go as far as going into the woods with a camera so he can get the feel of sitting on stand and see if he likes it some people just don't have the patience to sit long hours in the woods.Help him scout a few hunting spots so he will be ready when the season starts and you wont have to show him to his stand. You never know might make a great hunting partner for life and it never hurts to have more help dragging when you kill one. Just be careful a friend of mine worked with a guy who had never been hunting but wanted to try so we helped him get started and he got hooked now his wife doesn't like us much.
