Saturday, July 23 is National Day of the Cowboy. This event, organized 12 years ago, celebrates the heritage of these pioneers. From the development of the "Code of the West" to the expansion of the cattle industry, these animal herders influenced the frontier from Texas to the Rocky Mountains. The origins of the term can be traced back to Spain in 1725, but there's no better way to explore this moment in American history than with a book by Louis L'Amour. With 105 titles to choose from, including 89 novels, 14 short-story collections, and two nonfiction releases, L'amour's "frontier stories" are an excellent way to transplant yourself back in time.
