Its not just someone from another country that mistakes pronghorn for something else. We see them on every backpacking trip we take into the Petrified Forest. Once an excited fellow wearing his sweater tied loosely around his neck Ivy League style exclaimed about the elk! I tried to tell him they were pronghorn with the unique antlers. He exclaimed yes, they are elk. Lol I let it go.
On one trip there we came over a ridge and got the amazing sight of three pronghorn moving south to north at 60 mph over the rough terrain. That was one of those moments you never forget. It seemed a beautiful impossibility.
