A mechanical bull, also known as a rodeo bull is a machine that replicates the sensation of riding a bucking animal, such as a rodeo bull or horse popularized by Sherwood Cryer. It is usually powered by a variable-speed electric motor. Padded flooring is often installed around the equipment in order to prevent injury to those thrown off it.
It is a technical activity. Means to say descending on any rock with out any help. Rappelling is an integral part of climbing, yet is probably the most taken for granted aspect of the entire endeavor.
