That's the one part that I actually forgot in the book, I remember earth was blown up to make room for intergalactic highway, I know it was originally a radio series, I know that Douglas Adams is my favorite author and idol, but that is the one thing I can't remember, sorry man. But, thank the lord I found somebody else who liked his work, u are awesome by my standards, I'm going to travel around the forums, write again if u want, but I may not answer back.
