Like Valencia is a street circuit - or real street circuits, and out of how many venues
These are the 8 road courses and street circuits that they go to at the moment.
Streets of St Petersburg, Florida - uses some roads and one of the landing strips of Albert Whitted Airport.
Long Beach - the old GP course, also a temporary course built on the streets.
Watkins Glen - permanent circuit in New York State.
Mid-Ohio Sports Car Course - permanent circuit near Lexington.
Edmonton Street Circuit - temporary street circuit held at Edmonton Airport in Edmonton, Canada.
Sears Point Raceway - permanent circuit in California. It's now supposed to be called Infineon but I refuse to call it that.
Belle Isle, Detroit - temporary street circuit built on Belle Isle in the Detroit river.
So, 3 permanent road courses and 5 temporary street circuits.
Isnt it Champ Cars that did predominantly ovals (which is what was being discussed - not Indy)
Before the merger, it was the Indy Racing League that ran most of the ovals and the Champ Car World Series that ran mostly street circuits and road courses IIRC. Now that they're merged back together again, they run a 19 race series comprised of speedways and the above tracks where they have to - gasp! - turn right as well.
