WTXF, Fox 29, in Philly aired the show on Saturday or Sunday afternoons as filler, and not every week. The show did not air weeknights. This is before Fox had football. I seem to remember that it aired around 3pm, sandwiched in between movies. Sometimes they would do a double-run. We got WTXF on cable, and I could occasionally pull it in on antenna on my little 13" black and white RCA TV that I had in my room. (Those were the days of analog TV...from our house in south central PA, that little 13 inch TV could get Scranton, Philly, Baltimore channels, and more...)
I remember seeing the show for the first time and to me, it was a complete surprise that it existed at all. I remember taping Barker TPiR the following Monday to see if they had changed the set to match the neat Davidson set.
I seem to recall Aaron Sica saying that the show aired in the Harrisburg-Lancaster-Lebanon-York PA market on some station in the overnights, but I don't know if this was true, and I don't remember seeing it in the listings.
