Well, as young as I am, I still remember not only did my parents have to have a radio license, but I also seem to recall, a car cruising the neighbourhood, with some means of detecting which houses had radios. I think when we heard a radio show such as " I Love a Mystery" ( 1939 - 1944 ) it conjured up the scenes in our minds, with the characters Jack, Reggie, & Doc. The episode with the Temple of the Vampires was really scary! Our imaginations worked OVERTIME! No videos for us! My family was not affluent, but we were curious and had to be creative. Ruth
