It has been a long time since I was in Merced or any of the places around the Fresno area, but I don't think a track would contribute that much to the air quality. After all, it won't be running 24 hours a day 7 days a week like the freeways and highways do. Also if it will open up and draw the kids off the streets to race that should be a good thing. They used to have that near Vacaville and they had a huge amount of cars from all over the area that came to run at the track instead of stop light to stop light. I actually enjoyed watching those races as much as the regular scheduled ones as anyone could challenge anyone.
