While reading this book I always thought (or hoped) that there would be a sense behind all this. The book is really famous and also on the 1001 list so I was always looking for some hidden meaning behind all this. But, well, I couldn't find any.
The book is written in a quite fluent style so I read it pretty quickly. The first part still made some sense, but the second part lacked it entirely.
I was only fascinated by one thing: how can anyone take that many drugs and still be able to do anything? I don't think there is any drug the two protagonists didn't take (except maybe the ones that weren't invented then). That they were still alive after their trip (I love the double meanning :) is as much of a miracle as any of the Rolling Stones still being alive today!
