A friend and I share permission to hunt a 20 acre suburban farm near our homes. We each have our own stands on opposite ends of a crop field. Since it's close for each of us, it's often a last second hunt. Since we work the same schedule, we just text one another to make sure we're not interrupting something before heading out. Very casual.
Last year we mutually identified a corner of timber that seemed to be a travel corridor for mature bucks. Since neither of us had a stand in that area, we waited until winter to split the cost of a ladder stand and placed it in there. We also agreed that we would stay out of the area until the rut. The question then became, how do we determine who gets to hunt it and when? One possible pitfall would be for one hunter to monopolize that stand on the best days. Another pitfall would be that we both worry too much about being rude and fail to hunt it enough.The solution we came to is as follows:
We agreed to declare Oct. 30th "opening day" for this stand. A coin toss would decide who got to choose. There are 32 hunting days between Oct. 30 and the opening day of Iowa gun season (closed on this property). Picking even days gets you the first hunt on Oct. 30. Picking odd days gets you the next two, Oct. 31 and Nov. 1. Each hunter gets 16 total days. You can hunt as much or as little as you see fit on your day but you cannot hunt it on the other guy's day, even if he is staying home or hunting elsewhere. Before the toss we both realized that if he won he would pick even and if I won I'd pick odd. We put the coin away and shook on it.
Does anyone else have a system for sharing hunting spots with hunting partners?
