ABSTRACT:
A variably curved track-mounted amusement ride having at least one outside curve and at least one inside curve, each lying substantially within a vertical plane and each having an axis of symmetry which is substantially horizontal. Preferably, the top curve is an outside curve; and preferably inside and outside curves alternate with each other. Also preferably, before the first curve, between each outside curve and each inside curve, and after the last curve is a substantially straight segment which slopes downward. The vertical distance occupied by an outside curve is less than that occupied by an inside curve. The track can retain a cart which runs on the track no matter what the orientation of the body of the cart is with respect to the track. Any means that is well known in the art can be used to raise the cart to the beginning of the track.
