RHODA STREET BEACH, HOUGHS NECK, QUINCY, MASSACHUSETTSCharles F. Lindgren Photograph |
This is the beach that started my love of water, sand, and geology! I moved to Quincy at the age of three, and stayed until I was married at age 23. This was my beach. It is literally located at the end of Rhoda street. It spans a tad more than the width of the street. (Click the panorama image for a high resolution version.) |
