This possibly might have been stated before if it’s true, but I think a 1979 episode of Wonder Woman (season 3’s “The Starships Are Coming”) used the ‘Hazzard Square’ (Warner Bros. set...not the real-life Georgia location) as a small town Diana Prince/W.W. has to go to, to investigate UFO sightings/abductions.
FYI...this comment has nothing to do with the town square, but if you happen to watch this episode, it’s pretty bad...Lynda Carter was amazing as Wonder Woman (and other episodes are WAY better), but the plot of this one is beyond stupid!
Anyway, the square looks like the Hazzard one to me, but I could be wrong...some small town square sets used in TV shows back then, look kind of alike to me.
