Book excerpt: Throughout the years, the 76-square-mile island of Santa Catalina has hosted Native-American tribes, European sailors, American tourists, and even the Chicago Cubs. The island has survived both ecologically and culturally, resisting the temptation of becoming a Coney Island of Los Angeles. Through the work of its residents along with chewing gum magnate William Wrigley Jr., Santa Catalina Island is as beautiful today as it was when it was discovered in 1542.
