FoD79, the proposed street circuit is in Bricktown: the revitalized, old downtown area of the city. It's just south and east of the high rises of cureent downtown. That layout itself isn't anything fancy (a six-turn "L" shape), but the major streets in the area are certainly wide enough. And with two ~600m straights, and a roughly 1km straight, there will be overtaking potential.

Three races in California wouldn't be unprecedented. In fact, on the West Coast, IMSA ran Portland, Sears Point, Laguna Seca, and Riverside concurrently. VIR would be a nice addition to the calendar. Barber, unfortunately, just doesn't allow the room for the cars to really stretch their legs. And in this middle part of the country, the only potential, permanent venues I see are Brainerd and Heartland Park.
