Kimberly mentions a television show from the 1970s called the Medicine Hat Stallion  starring then teen heartthrob, Leif Garrett. The Medicine Hat Stallion was actually a made for television movie from November 1977. It takes place in pre-Civil War Nebraska Territory with a 15 year old son and his father, mother, and Grandma Lundy. His father treats him poorly as he is unhappy with his life at their prairie trading post. Garrett's character raises a foal that was left at the trading post in lieu of payment of goods. When the horse becomes old enough, Garrett's character and the horse earn a job with the Pony Express. It is through this tough job that Garrett's character earns the respect of his father. The movie was based on the novel San Domingo, The Medicine Hat Stallion  by Marguerite Henry. It was a Newberry Medal winning book.
