Amusement rides, sometimes called carnival rides, are mechanical devices or structures that move people to create fun and enjoyment.Rides are often perceived by many as being scary or more dangerous than they actually are.This could be due to the design, having acrophobia, or from hearing about accidents involving rides that are similar.[2] They are common at most annual events such as fairs, traveling carnivals, and circuses around the world.Sometimes music festivals and concerts also host amusement park rides.
