Query: Dirt Bike Racer Review by Ashton Bradford

Skill and luck, at least that's what Ron thinks. Dirt Bike Racer is about a kid named Ron who finds a mini bike at the bottom of a lake while scuba diving. He wants to replace all the parts, but he doesn't have any money. He gets a job working for Mr. Perkins. He finds out Mr. Perkins use to race. Ron finally makes it to a race, but wrecks. I think the theme of this book is sports. The author of this book is Matt Christopher and he always writes about sports. What inspired him to write books, was a piece, someone wrote in high school wrote. It inspired him because he wished he could write like that some day. Matt Christopher has written many books some of them are Peach Street, The Extreme Team, and Soccer Cats. A quote he has gone by is "Good judgment comes from experience, experience comes from bad judgment." I think the quote is good because when you do something bad you learn from it. I recommend this book because it's a good and exciting book.
