Not to split hairs, but Circuit Giles Villeneuve is technically a street circuit, and RA, Sonoma, Mosport and the Glen technically don't have SAFER barriers, to the best of my knowledge.
NASCAR needs a new market to spread thin towards and widen their lameness in. If the hippies will let them race there, I'd say the NW Market and Portland Int'l would be the next place for them to tap into. Long shot maybe.
At least this year, the road races in the top 2 are scheduled to where anyone can participate:
- Sonoma Cup Race is off weekend for Xfinity (<---sounds weird)
- The Glen is a shared weekend
- Mid Ohio is the Saturday before the Michigan race: convenient enough
- Xfinity RA is Cup off weekend on a Saturday and Trucks at Mosport is the following day
Too bad Taz ain't around....
