Had a creepy find yesterday at that health club I posted about last year. Our group of five discovered it last September, and I went back alone in November for a GoPro walkthrough. About a month after that, I was going through pictures, and noticed something - what appeared to be an open doorway that we had somehow all completely missed, despite having walked right past it many times.
Yesterday I had the chance to briefly dip back with one other person from the original group. Turns out there was a door there, but it was pitch black inside, with tons of insulation hanging from the ceiling. I poked the camera in an took a pic. We weren't disappointed.
Apparently they had a daycare.
