One of the best ep's, with all the ingredients: Lucas' life threatened, fancy rifle shooting, bad guy due for his come-uppens, cute Mark, pretty woman (see Wikipedia for fascinating but tragic life of Joanna Moore, mother of Tatum O'Neal), yet full of typical subtle but effective morality and life lessons (even for the gunslinger at the end, who's life and ways is probably saved and changed by Lucas McCain). All packed into less than a half-hour. Good example of why this show is a classic and will always be.
