Photos: Flying Turns toboggan coaster under construction at Knoebels

Knoebels amusement park in tiny Elysburg, Pa., has spent the last five summers trying to build a working version of a 1930s-era ride known as Flying Turns.The ride is a trackless coaster featuring a toboggan train that glides freely like an Olympic bobsled through a twisting wooden chute.
