Sounds like Bob was under the impression that he was supposed to build the backstop at the old tire location, and apparently he thought he was living up to his agreement. I believe what you have here "is a failure to communicate". I'm not to sure I can blame the guy if he honestly thought he was doing what was agreed upon. Perhaps you and your husband should have stipulated to Bob, exactly where you wanted the backstop to be located and it probably wouldn't have hurt if you had moved the old tires into that spot at the time the original agreement was made. I'm sorry for your son's loss of a spot to hunt; but at the same time, I believe a portion of the blame rests on you and your husband for not establishing the location from the beginning.
