The 1970s were the last golden decade of the old Grand Strand, a time when Myrtle Beach was still a laid-back Southern seaside town before high-rises, mega-resorts, and theme parks reshaped its skyline forever. Families rolled in by station wagon, cruising Ocean Boulevard past neon-lit motels, mom-and-pop arcades, and open-air pavilions where beach music and the shag drifted through warm salt air. The Pavilion Amusement Park hummed with the clatter of wooden coaster cars, boardwalk snack stands sold saltwater taffy and fresh-fried seafood, and modest oceanfront cottages sat where towering condos stand today. This documentary-style look back revisits the sun-bleached postcards, chrome-finned memories, and unhurried rhythm of a coastline on the edge of change, before the crowds, the concrete, and the concession to modernity turned a beloved beach town into the tourism giant it became.
