Long before the days of giant theme parks, the United States had many amusement parks where families gathered for a cool escape on a hot summer day. Celebrate these pre-Disney parks with visits to Playland in Rye, New York; Holiday World in Santa Claus, Indiana; and California’s Santa Cruz Beach Boardwalk, where vacationers can still reach for the brass ring on the merry-go-round. Rick Sebak narrates the special, which also checks out some old wooden roller coasters and other classic rides.
