Weird yes, great yes! Over the past few years, I've really grown like this well-crafted show with its out-of-the-box plots and great guest stars. This episode just happened to be a little more out there than most, but science fiction vs. The old west always works for me! I've seen a few of these types of episodes where McCullough, scouting ahead, runs into some real oddballs, this time a European immigrant and his son getting ready to climb one of the Rocky Mountains. Unfortunately, they get caught in a blizzard and end up seeking shelter in a cave that's inhabited by something very strange indeed...
