I adore Hitchhiker's Guide and the other Douglas Adams books. I grew up reading those books, then later listening to the audio books. And of course, I played the Infocom game on my Commodore 64. Anyone else remember that?
The books really seem to have a very 80's feel to me, but maybe that is just because I associate them with my childhood.
I'd certainly go to any park that used the theme. Memories, memories .....
