Switchback, the only modern wooden shuttle coaster in existence, opened at ZDT's amusement park in Seguin, Texas on October 17. This unique coaster, like a boomerang, begins the circuit going forward and then does it all in reverse. The steepness of the drop and 87% angle of ascent are bound to ensure a thrilling ride. This looks like another winner for The Gravity Group, probably best known for The Voyage at Holiday World. Photo courtesy of ZDT's Amusement Park.
