I don't remember watching much TV during the 70s. I may have done, but I just don't remember much about it. I did become addicted to The Rockford Files, but that was later, in the early 80s, when it was in syndicated reruns. It gave me something to look forward to in the afternoons.
Now when I catch an episode it makes me uncomfortable because of the clothes. I think how hot and sweaty everyone must have felt wearing all that polyester in the Southern California heat.
