The Cheyenne Frontier Days Rodeo is an annual rodeo held in Cheyenne, Wyoming. It is likely one of the largest rodeos on the earth and attracts over 200,000 guests annually.
The rodeo was first held in 1897 to have a good time the opening of the brand new Union Pacific Railroad line by way of Cheyenne. The rodeo has been held yearly since then, aside from a couple of years throughout World Conflict II.
