I agree with your decision. Most hunters dont hunt by themselves. They usually have one-four buddies that hunt with them. Plus, once the word gets out that you let so and so hunt then you will be faced with more people asking you to hunt. At some point you will have to say no. Its hard to do but you dont want to say yes then wish you had said no. I had to tell a guy once that he could no longer hunt my property because there was just too many people hunting. He did not take it well.

We are only talking about 15 acres here. I would not consider keeping 15 acres to yourself greedy.
