On a recent trip to Eminence, Missouri I got to see two of the three wild horse heards roaming that county. The herds are federally protected and have been around for decades. The first heard I saw had nine members, the other one had around 18.
The three herds stay in the same general area, but it's a big enough that a little bit of luck and/or persistence is needed to see them.
