Piccolo Madonie Circuit "Targa Florio" (1951-1977) 44.6mile
Ascari Race Resort
It's owned by British marque Ascari, ad I believe it's located somewhere in Spain, but I could be wrong.
Obviously, there's four possible configurations: CIrcuti 1, Circuit 2, Circuit 3 and a combination of the three, much like the Gotland Ring in Sweden.
Either there or courses made out of what's at the NE Philadelphia Airport or the area around the Sports Complex in South Philly.
If you also like, maybe a street course out of the area between the Stadiums and the Inner Harbor in Baltimore. They have the Preakness Stakes there every year, why not something with horsepower as well?
