Casper, a 2014 stallion out of Shale by the legendary Gray Ghost, became a bachelor in November of 2017. He ran with several other bachelors through 2018 and into 2019. In the summer of 2019, he began to spend the majority of his time with Former Band Stallion, Cloud after he lost his band.
In 2021, Casper worked his way into Teton’s band. Over time he took control of three of Teton’s daughters, Archer, Bee, and Berkleigh. He currently runs in a double band with Stallion Teton. They are often seen together in the same area of the Park, but there is a noticeable separation between the two bands.
