Some of the popular rodeo events are bareback riding, steer wrestling, tie-down roping, saddle bronc riding, team roping, barrel racing, steer roping and bull riding. The events are staged in arenas that vary in size from a few hundred to over 20,000 seats. The rodeos are usually held on weekends during the summer months, and often on holiday weekends. Rodeo events have been a part of rodeo culture since the late 1800s. The National Finals Rodeo (NFR) was started in 1905 by brothers Joe and Frank Wright as a way to determine the best cowboy in the country. The NFR is the most prestigious rodeo event in the world, and is held in Las Vegas every November.
