I just finished a book by Rinker Buck about how he and his brother drove a covered wagon and three mules more than 2000 miles along the Oregon Trail from the St Joseph Missouri to Portland Oregon. Chapter three was about the history of mules and their importance in North America - a bit of history left out when I took American History in college. One mule named Royal Gift, was a gift from the king of Spain in 1785 to George Washington - British colonists, prior to the revolution, were not allowed to import large breeding jacks from their breeders in France and Spain, dire enemies of Great Britain. Just one of the facts I found interesting in this great tale of history and adventure, broken wheels, wagon wrecks, and all. If you find it as entertaining as I did, please leave a comment here.
