You've told them its a doe only hunt.......thats fair, especially since you, your son, and two friends will be hunting there regularly.

One last thought, I've learned over the years to be extra cautious to whom I ask to hunt with me. A friend of mine who I introduced to bowhunting went with me a few times last season, but never once has he asked me to tag along with him on properties he can hunt, though I did help him trail the first deer he shot.
