Here’s the shot of the “Hazzard County Fair Grounds†(“Fair Grounds†appears as two words on the sign) that CDoherty mentioned. I have to agree that the building in the background is about the size of the Boar’s Nest, and the back of the Boar’s Nest does get used in later episodes (pictures to come), but I can’t match the landscape to the location. Even back on a 1980 aerial view the area behind the Boar’s Nest was grassy and quite small. On this picture you can see a row of telegraph poles with distinctive street lights running down the side of the fairgrounds. I haven’t seen these anywhere on the ranch. I think there might be a railroad track on the other side of the fence; there’s definitely a road or track because a car and someone on a bicycle can be seen traveling past at various points. If there is a railroad it may be part of the Filmore-Saugus line that was slowly abandoned after the Santa Clara River trestle was washed out during a flood in 1976. I’ve been tracing its route on old maps and it’s easy to forget that Santa Clarita didn’t exist until 1987; before that it was Canyon Country, Newhall, Saugus and Valencia, and mostly open farmland. In the background of this picturel you can see some dark cylindrical structures on the hill. I don't remember seeing them in other episodes, and haven't found them on any aerial maps. Looking in this direction you can see one of the ubiquitous water towers above Jesse's head. I wondered if it might have been a real showground, but found nothing on Google. I think, at least for now, this location will remain “unknown†unless anyone can persuade me otherwise.
