It seems that several aspects of the show were simply rolled over from the radio drama. Thus the "This is the Yukon..." intro and sound effects that were appropriate for radio but did not always match the picture. Howling wind on a bright cloudless day is a bit risible but the audio simply isn't as important when there is a picture involved and I just tune it out. It's just like when King is "attacking" a bad guy and it is clear that he is just playing (insert growls). Rex really couldn't be used in a winter scene and even if horse travel were story-plausible, it would detract from the important dogsled theme. That is also why winter prevails. This is the Yukon after all and the struggle against the harsh elements provides a lot of the drama and chance for heroics. I would have liked to see more participation by other mounties and some activity within the judicial system. Maybe Preston saying something like "Book 'em constable, Murder One!" And why did almost all of the (younger) women have to be beautiful? Given the odds in 1890 Yukon, any woman with more than four teeth would have been a catch.
