Same setting, and had been #4 rated show in '68 and '69. Few shows survived the loss of the lead, but that one did till the Purge.
It was set in Mayberry, and IIRC the first episode had Andy, Opie and his new wife leaving the area.
Always liked that show (had a thing for Arlene Golonka) and watched it religiously...
HAWAII FIVE-0 was doing quite well and I feel helped bring along other shows like HILL STREET BLUES...
