In GT5 that was the case as it was modeled after PD's new headquarters in Fukuoka, with the setting based on the Hakata port town and road design coming from the Fukuoka expressway. In the distance just left from the starting straight, a city scape could be seen across the ocean, and the vegetation is relatively green. It was originally given the PDI flag as it's assumed as a fictional location. But it has since been changed to a US setting, with the USA flag to prove in GTS. More evidence is how the airplanes sport only a single Blue Moon Bay livery that's based on the classic American Airlines colour scheme, suggesting SSRX is that airline's storage airport and hangar. The cityscape in the distance is gone and the scenery is noticeably more arid and dry. Fisherman's Ranch was given that name because the map creator's name in English means fisherman. There is an interview somewhere either in GTP or elsewhere that sheds light on this. It ironically has no relation to embodiments of water. Not an oversight. Those animations were done by PD. They have the knowledge behind the race course after all. If that dot's in GT7, it's definitely the same course. This is evidence that the Arizona dot is Fisherman's Ranch. Thank you for providing this.
