1. Leave gates in the manner you find them. They are open or shut for a reason.
2. Don't give gate combinations to anyone
3. Pick up any trash you see, no exceptions.
4. Report anything damaged: fences, gates, water troughs, etc.
5. You see a log in the road, you move it completely out of the way. Don't drive around it.
6. Don't drive around in the mud and rut up the roads.
7. No neck/head shots on deer.
8. Figure out where you're going to sit the night before. Everyone knows where everyone is.
9. Figure out how to drive to stands to avoid disturbing anyone.
10. Agree on when to go to the stand & when to leave. (as other have said)
11. Somebody wounds a deer, everyone helps to look for it.
12. No alcohol in the stand or driving around. Camp only after hunting is over. No dumbassery.

14. Everyone knows the address, GPS coordinates, etc. of the place for emergency responders.
15. Everyone cleans up every time. No mess is left and no shirking.

17. Guests must be agreed upon and vetted
18. Everyone signs a hold harmless agreement
19. No dogs running around
20. Some sort of agreement on shooting hogs, coyotes, coons, foxes, bobcats, etc. What is policy?
21. Everyone learns to age deer, and adheres to the standards of harvest agreed upon.
22. What is the policy on "claiming" a deer? ie: Bubba's been hunting that drop tine buck all season. Skeeter is out for the first time all year in January and kills "Bubba's drop tine buck". Bubba now hates Skeeter and camp tranquility is ruined. Get this mess sorted out and stick to it.
That's off the top of my head.
