@DallasBarnett I was obsessed with it as a small child. Arthur C Clarke's World of mysteries was the book that introduced me to spontaneous combustion, poltergeists (so 70s), talking mongoose, cattle mutilations and crystal skulls.
@DallasBarnett ooo, is that the one inside the mountain?
Also Area 51 also fascinated the crap out of me
@DarbyBGoode The one inside the mountain is NORAD .. Hangar 18 is the nondescript hangar at Wright Patterson AFB where they supposedly keep the Roswell UFO
