Standing before a building that has been part of his life since childhood, Bill Cassidy looks out onto South Street in Bridgeton, New Jersey, a town he's known for all his 91 years. He's something of an elder statesman in Bridgeton these days; he was chief of police for a time in the fifties, and he still serves as the town's zoning officer.
      That's the old Pretzel Amusement Ride factory in the background, where Mr. Cassidy and his father manufactured the world's first and most well-known dark ride. The former trolley barn now houses a bustling fabric distribution company, with nary a trace remaining of the machinery or craftsmen and artists who produced the varied procession of Pretzel rides that emerged from its doors over five decades, nearly 1500 of them, bound for amusement parks and carnivals all over the United States and beyond.
