An authentic chuckwagon -- the cook's wagon that accompanied cowboys as they drove cattle across the dusty plains of the early American West -- on the rodeo and Frontier Town grounds at the Cheyenne Frontier Days in the Wyoming capital city. The Western celebration that is viewed by an estimated 200,000 onlookers, including throngs of tourists, each year in a city of 62,000 people (as of 2015) includes one of the West's most celebrated rodeos, American Indian pageantry, free pancake breakfasts, several Old West-themed parades, and other events. Cheyenne Frontier Days have been a mountain-states tradition since 1897. Photo by Carol Highsmith, 2015.
