drover was more of an Eastern and European designation, I think.

I could ask one of the locals. Living in Missouri is living in the heart of "mule country". I pass a handsome "buckskin" in a pasture with five other mules each morning on my exercise ride. Spose I could ask him?!

When we move up to Wyoming we hope to acquire two horses and at least four mules. They are slower but more reliable, especially in the high country.
