Query: GO JR!

I bought this book for my husband and he just loved it. What a great story about his rookie year. It was great fun to read. Jr shows his wit, candor and honesty. He tells it like it is. It is a view behind the scenes of NASCAR. He explains what it's like to be a driver in the greatest sport and a son of a racing legend.
