Flight of Passage by Rinker Buck (no relation to Bob Buck from North Star over my shoulder...also a good book).

Just finished this on vacation. Great read about two teenage brothers who bought a PA-11 Cub for $350 (1966), restored it and flew it from Jersey to LA. Fun coming of age tale with lots of great aviation adventure of flying across lands they'd only ever heard of in a book. I had a hard time putting it down but I love GA and the romantic nature of this type of stuff.
