How do you stop good friends from fishing your pond without hurting their feelings? I've let friends come when they ask but now they want to come often and bring a friend of theirs. What are some good excuses why you can't let them fish anymore. I don't want anyone but my immediate family fishing but I don't want to hurt feelings either.

Are there some approaches that have worked for you that kept your friends close but not coming to fish. If the friend would come once or twice through the season there wouldn't be a problem. Honestly I don't want anyone but my family at the pond. That may sound selfish but thats how I feel.
