RE: To each his own, but I sure wouldn't
Great post.
I think you're admirable for wanting to not come across as a jerk, but I'd stress to keep in mind that you're the landowner. What I mean is that what you say ought to go, and whoever gains permision via you should respect your wishes. I know I respect every single wish of the landowner where I hunt. I've even gave up some evening hunts to help him work on his combine and other things.
Bottom line is anyone you invite in is a guest, and he ought to respect your wishes to the upmost. Whatever your goals for your deer herd ought to be taken into consideration. The guest should just feel fortunate that he's allowed on your land at all, and know that privilege can be taken away at any time.
