Also around 1976, I spent many long hours passing the time in the lobby, and halls of the Hotel Colorado in Glenwood Springs CO. My mother was taking upholstery classes in the basement of that hotel which spanned a few months.
Apparently this hotel is haunted. My brother and I used to shuffle our feet on the wool rugs of the lobby and holding a small piece of metal rod we would touch one of the side panel screws of an arcade game down the hall called tanks or something. The game would receive a static shock and immediately start a new game as if I'd just fed a quarter.
As a 6 year old, I just thought it was cool, I never saw anything that scared me there, even in the basement. It is now listed as a haunted hotel.

After watching
The Shining with Jack Nicholson I developed a new appreciation for my old haunted hotel.
