From its slip at the foot of Marion Street in Seattle, the broad-beamed ferry swings west across the Sound to Bainbridge Island. Home and vacation-place of well-to-do business and professional people, university instructors, and artists, Bainbridge Island might be called the aristocrat among the islands of Puget Sound. Many beautiful residences are scattered about the 11-mile-long island; summer camps are strung along the beaches. At the height of the vacation season in the 1940s, its normal population of 3,000 expanded to 6,000.
