Our lease in Alabama with Westervelt Land Management defines a limit of 1 hunter per 100 acres.
The club I was in previously worked out to about that.
my opinions:
40 acres per family member, or other group who has to get along subject to the rules of a patriarch or other single point of decision making, would work out, becasue you don;t have any other choice.
If the club is a made up of equal equity members (like a lease), you may need to spread out more and have fewer members (100 acres per hunter).
