NOR CAL!!!!
First off I can't go riding with you because I'm in the desert. I will be home to ride around Thanksgiving.
Where to ride...... (get a pen and paper)
Prarie City - Nice Facilities and decent size. Crappy MX track though. It's a nice afternoon place.
Forrest Hill - Bit of a drive but lots of trails. Alot of hill climbs, wooded, very nice. Good place to spend a full day and get away from the heat. It's all trail riding though.
Carniege - Never been but I hear it's mostly hill climbs. I have a friend who swears by this place. I am planning on going here in the spring.
Chico - Forget the name of this place but it's a full on MX track. They race dirt bikes in the morning and quads in the afternoon. I have heard lots of good things about it.
Nevada - Pull off the highway and enjoy BLM land. I prefer Yerington and Weeks. That's more of a weekend adventure.
Pismo - Duning.
