TOD: I had no favorite radio shows when growing up. Everything was Top 40. My dad used to gripe about there being no local C/W stations.
When I was in college (1966-70), and had my own car, I discovered a station called "W-O-W-O", and it played great music all day long (when I could get the signal, that is).
I've never known the particulars, but I reckoned there were certain times each night when WOWO could boost its signal. Otherwise, you played heck finding many stations still on the air. It was out of Fort Wayne, Indiana, which was, to me, one of those exotic "northerly mid-western cities" from where I was in South Cackalackey.
