Starvation Mountain by Robert Gilberg

Jim Schmidt, a high-powered computer whiz decides to take early retirement from the stress of the rat-race and build his dream house at an avocado ranch on Starvation Mountain, near San Diego. Never married, Jim is well off and content with his passion for owning and riding motorcycles. The mountains around Southern California provide wonderful trails for his riding. When Jim meets a younger, forty-something, Penny Lane, the connection is instant and enjoyable. But Penny is tied up with an old high school buddy who seems to be on the wrong side of the law. Unintentionally caught up in a vicious drug gang web, Jim and Penny find themselves on the bike ride of their lives, following the old Route 66 trails of their favourite movie, Easy Rider. Starvation Mountain is a thriller that combines 70's pop culture with a love of motorcycles, especially Harleys.
