There comes a time in a young man's life when Halloween, like Gregor Samsa, goes through a metamorphosis from something familiar to something vaguely unsettling. One year Halloween means providing for the Dentist's retirement, and suddenly, the next year, it is a venue for impersonating Bela Lugosi. While trick or treating was fun when you are a "little kid", and visiting the local Haunted House was okay when you were only a kid, things change so that actually MAKING a haunted house, or as close as you can get to it, becomes a really cool thing.
I remember a Halloween in the early 1960's when I went through this change. Since I was the studious sort, not the juvenile delinquent type, my Haunted House was well... a little weird. After all, one must admit that a Volcanic Pumpkin is a far cry from a Haunted House. I don't remember where I got the idea, but I think it must have been from Mr. Wizard.
