2010 was a successful year for the santa cruz beach boardwalk. At 2:40 this afternoon, the 1-millionth roller coaster rider was recorded. The million-rider mark was passed when a train of 24 people set out on the Giant Dipper. The last time the million-rider-mark was passed was in 2002. Since its opening in 1924, roughly 58-point-4 million rides have been given on the giant dipper, which is a national historic landmark.
