I posted a couple of photos on the Photo Critique forum, a couple weeks ago, from my So Cal mtb roadtrip. I just finished posting a whole report, with lots more photos, on the Mtbr.com Downhill forum. There are photos from San Dimas, Orange County, and Santa Barbara. Don't look if you hate mountain bikes!
