I used to live near a grain loading facility on the Columbia river in Washington where they would unload grain from train cars and load them onto massive ships to go overseas. There were some monster deer that lived at that place and like your power plant, never left.The power plant I am working at has monsters running around, and they dont leave the property. Completely protected and have everything they need.
They do. I've never found my shooting range to be deer repellent for more than a few minutes.Deer get used to the sound of gunfire. I've had to stop shooting several times and walk down range to chase deer and turkey off the shooting range where I shoot.
