Wow, what a read and what an adventure these guys had. Set in the mid 90's it still translates to today (if you remember there were no cell / satellite phones, GPS Navigation etc available)
With all road trip books I read, it tends to shrink or speed up at the end as if they are rushing to get to the finish, hence only 4 stars. I recommend you read the glossary first, at the back, to get a handle on their "buzz" words, whilst reading the book I started using "blend" in my daily converstation and no-one knew what I was talking about.(no real change there then anyway)
