RE: Ethical/Legality?
Many states have laws covering the retrieval of game, and laws concerning the waste of game. This post should be a wake up call to those hunting in states where you might be denied access to land should it be neccessary to retrieve game. Quit bitching on the internet, and start making calls, and writting letters to the officals in your state.
As far as hunting on private property goes, if one has permission to hunt there, then they can hunt where ever they please. Be it forty yards from the posted land, or forty inch. The posted signs only control the hunting on your land. Most hunter place their stands where they are seeing sign. If it happens to be near the border then it happens to be near the border.
