And interestingly, Lt. Col. G. A. Custer was fond of thoroughbreds and whippets.
Well, they did have Thoroughbreds in this country in the 1860s, so Custer on TB is not an anachronism. And I don’t really mind Aragorn riding around on a baroque-breed horse, the Lord of the Rings is fantasy. I tell you what, though, cowboys in the nineteenth century surely did not ride Appaloosas, and there were no Aps in the War Between the States.
