Rocket Rill is a physically challenged interplanetary pilot who, in his retirement years, simply loves playing the game of golf. His friend Sidney (who lives on Mars) has taken up a game with his Martian friends that is eerily similar to golf, but something is really wrong with their methods and behavior. So, Mr. Rill has a huge challenge ahead of him: to teach Sidney golf etiquette! Learning ensues in a very educational and funny book. Certainly great for children, I know this because I have taught golf for 30 years. And it is fun for everyone.
