When it’s not a Halloween attraction they let you stay overnight and do “paranormal” investigations. They allow you into 3 of the buildings, the rest are closed off probably due to deteriorating construction/unsafe air quality issues like mold. My ex and I had an absolutely blast running around there one night exploring. Convinced her to turn off the flashlight in the basement and just stand still, it was interesting, maybe it’s just the heavy concrete and overall oppressive architecture of the space but you could really feel a sense of uneasiness down there!
