George B. Quatman acquired the west side of Sandy Beach Park in 1957 and the east side in 1962, and the park was renamed San Juan Amusement Park and became alcohol free. Even so, bars and restaurants along the harbor remained busy, and on the evening of July 4, 1961, revelers resisted bar closings, leading to the first of several annual riots. Fights, property destruction, and rowdy behavior became common on July 4 holiday weekends, and for almost a decade the park and the Russells Point community struggled with a reputation blamed on outside troublemakers as attendance and investment declined. In 1967 the park was sold to Venice Amusements and renamed Indian Lake Playland. Its Danceland ballroom became the Black Pearl, and rock and roll acts including Frankie Valli and the Four Seasons and Herman’s Hermits appeared there. By 1972 the violence had subsided and the community’s reputation improved, but newer and larger parks elsewhere in Ohio and easier family travel further reduced attendance. Indian Lake Playland gradually closed, with the Midway, including the Fascination and Skee-ball games, the last attraction to shut down at the end of the 1975 season. Only the Carousel found a new home at Six Flags Amusement Park, while rides such as the Thriller coaster, Tilt-A-Whirl, Paratrooper, Orbit, and Love Bug stood abandoned as weeds and vines overtook them. Through the late 1970s the property became derelict until local businessman William Bill Reed bought it. After the sale and redevelopment announcement in 1981, movable remnants were taken away, the wood and steel structures were demolished by the end of that summer, and the site eventually became Harborside and Harborside Lagoon condominiums along with new retail and food businesses. Today only the arched bridge over Russells Point Harbor remains as a surviving link to the amusement park’s past.
