I would rather any of these US FIA Grade Two circuits spend/get the money to upgrade to Grade One before a US city street race, but that won't happen because profit. Some would never happen anyway though, e.g. Laguna Seca.
Barber Motorsports Park
Lime Rock Park
Mid-Ohio Sports Car Course
NOLA Motorsports Park
Portland International Raceway
Road America
Road Atlanta
Sebring International Raceway
Sonoma Raceway
Virginia International Raceway
Watkins Glen International
WeatherTech Raceway Laguna Seca
Agreed, the proposed penis Miami track looked terrible.
