Somehow this has missed my radar my whole life, but it's been running for 47 years. Unfortunately, it's about as difficult to see as a lunar eclipse. You not only have to get yourself to Bristol CT, you also have to attend during their extremely limited hours; five days out of the whole year, all of them in October. You have this Friday and Saturday to get up there, and then Halloween day, then that's it.
I met the guy, or one of the guys, who runs it at last weekend's convention. Buy one of their DVD's and support the museum. More info here.
