Custer

Nitpick: strange that Melinda Terry has the same last name as her brother as it's specifically stated in the dialogue that she's married and has two children.

In this series, Custer is stationed out of Fort Hays, Kansas. However, this particular episode involves a rather quick trip into the Black Hills, which is in South Dakota. They made amazing time on horseback, considering that they had to cross Nebraska to get there and back.
