Big Dipper (Luna Park Sydney): The Big Dipper was a wooden roller coaster operating at Luna Park Sydney from 1935 until 1979.  It was demolished in 1981.  First constructed in 1930 to an American design, the wooden Big Dipper roller coaster was a mainstay of Luna Park Glenelg during its four years of operation.  The ride was dismantled and shipped to Sydney when the Glenelg park went into voluntary liquidation in 1934, and became the biggest attraction of the newly opened Luna Park Milsons Point (which was later renamed Luna Park Sydney).

Luna Park, Schenectady: Luna Park was one of several names for an amusement park that existed in Rexford, New York, near Schenectady, from 1901 to 1933.

Constructed around the Grand View Hotel (built and opened by Jacob Rupert in 1901), the park was similar to Ingersoll's other Luna Parks in which it was a trolley park with roller coasters, picnic pavilions, carousels, a fun house, a roller rink, a concert shell, a dance hall, a midway, a Whip, and a shoot-the-chutes ride which presented itself at the park entrance adjacent to a station of the Van Vranken electric trolley line.  Roughly seven decades before the Skycoaster rides that now dot various United States amusement parks, Luna/Rexford Park featured an aerial swing ride.
