Each December since 1885, The Cowboys’ Christmas Ball is held in Pioneer Hall. Popularized by Michael Martin Murphey’s musical rendition of the “The Cowboys’ Christmas Ball,” a poem honoring ranchmen of Texas written in 1890 by William Lawrence (Larry) Chittenden after attending one of the balls. Check out the “Cowboy Dance” art by Jenne Magafan in the U.S. Post Office.
