Abstract
Abstract A slide is provided, preferably a water slide, which is self-supporting and may be erected adjacent any amusement location. The slide of the invention provides a substantially longer sliding surface for the amusement of users without requiring an inclined ground surface for support of the slideway. The slide incorporates a pathway for ascending the slide, and preferably a water supply facility to enhance the sliding action. The entire structure is supported on one or more vertical supports resting on the ground.
