I've got my location all picked out. Large concrete building, windows and doors are easily boardable. Building itself is segmented by steel fire doors, so even with a break in, can retreat. roof access for sniper positions, building is surrounded by about 5 acres of clear ground. The building runs on propane, with a couple thousand gallon tank that is kept at least half full at all times, also has diesel and gas tanks on site, along with some large trucks, one being a water truck with 3500 gallons of fresh, treatable water.
