Ladies and gentlemen, I give you a glimpse into my childhood.
In the 1960s and early 70s, television was limited to black-and-white and 3 channels. One of those channels, CBXT, an outlet of the CBC, carried many shows that became iconic for me.
One such show was The Forest Rangers. Here's a video of the opening credits:
Although it was shot in colour, we never saw it that way, so the red serge of the Mountie's uniform and the verdant green of the woods were supplied by our fertile imaginations. It's odd to see these in colour now.
Here's a clip from an episode. It's a shot of a television screen, so the quality is poor, but I think it gives a feel for watching the series back in the 60s.
