I remember buying The Demonologist at Fay's Drugs in Lansingburgh, NY when it came out, early '80s maybe? I was way into the occult as a kid, and "forteana" before I knew the term. UFO's? I like the "classic" period before all the abduction nonsense. But Bigfoot's my pet interest of all that stuff, it comes from the '70s thing, it's organic, and it's SORT OF possible. I'll send a video I made, "Best of Bigfoot."
I posted a similar thing somewhere around here about panic, from Pan, when you're walking in the woods by yourself and you suddenly feel something watching you and you bolt for your life, but you never see anything. Primal.
