This is an absolutely massive location, parts of it still in use. While we were exploring, 4 police cars showed up. RevSM and Allva were with us for this trip and Rev and I had been standing near an opening looking out over the complex when I looked out front and noticed two police cars parked next to the fence! Thankfully they were after two guys that were trying to steal a massive piece of metal and not after us. After two SUVs pulled up, presumably caretakers who brought the metal piece back inside, everything was squared away and they all left. Still, we were slightly freaked out so we left without getting to finish exploring the whole place. This is definitely a place I want to go back to.
