It's been years since I read it, back in my high school days.  Fantastic book from what I recall, though I'm sure I didn't appreciate it to it's full potential; Being in the mindset of it as merely "school reading."
Just last week I was compiling a list of books I should read, and realized it's time I plow through more Vonnegut.  Unfortunately, all I am versed in is Slaughterhouse 5 and Breakfast of Champions, * .  Cat's Cradle seems like a good choice after reading reviews of his oeuvre.
