I think you should be straight up with the guy and let him know how you feel about his dirty deed. The two guys who have brought me into their hunting world and favorite places to hunt are very protective about their spots. They discovered them over 20 years and do not want them to be advertised to the world. I replaced my brother who passed away and then happened to get a deer of a lifetime this year on my first shot as you know. We were the only ones in the area and that may be attributed to the fact that they are so protective about their spots. As much as I would love to share the information, I do not want to violate their code.
