S1E23: Desert Justice

When a tough U.S. Marshal from California arrests a Ponderosa hand, Dave Walker, for murder, Adam and Hoss go along to make sure their employee reaches Los Angeles alive. In one scene, Adam is dressed in black for the first time. In another, Hoss, upon seeing Southern California for the first time, remarks, "It sure ain't never gonna amount to much". Later, Adam makes an amusing reference to the chow Joe says he was forced to eat in "The Last Hunt".
