Back in 1908, Hawaiian Cowboys competed in the Cheyenne Frontier Days. In the new book, Aloha Rodeo: The Three Cowboys, the World's Greatest Rodeo, and the Hidden History of the American West, co-author David Wolman explores how and why Hawaiian Cowboys came to compete in the rodeo. Wyoming Public Radio's Kamila Kudelska asked Wolman if the two cowboy cultures were different in any way.
