Not exactly in the 909 but worth mentioning is 4 Fun Hobbies and Raceway in Hesperia. It takes 40 minutes from the center of Corona to the gates of this huge track with incredible traction, awesome drivers stand, covered pits with tables, chairs, air gun, power, and fully stocked hobby shop.
The people (Scott & Gail) running it are great.
Racing on the 4th so come check it out.
