I did NOT like Inside the Postal Bus by, I think, Dave Barry.
I'm reading a book right now called 23 Days in July, about Lance's 6th TDF. Like a lot. Also about other riders.
I just finished "The Rider" by Tim Krabbe, which was very short, and I liked it a lot.
Travels With Lucy, by Chris Buerki. About a guy who rides from Florida to California with his dog in a trailer.
