I saw your post asking about any flat trackers out there. I feel bad because you didn't get any response. Myself and several others worked hard at putting races together here in Southern California. It started first in Central California but died quickly there. We had minibikes racing going on four dirt tracks here! We really had some great races but the turnout faded to the point where only 3 people would show up. So the last official race ended at the beginning of 2011. Earlier this year we put on another race at a local practice track. We had a decent turnout but I don't think it will ever be something steady. There's just not enough interest. Anyways, I thought I would just write you to let you know what we did.
