Mountain biking trails in/near San Diego

Anyone in San Diego mountain bike? I usually go to Mission Gorge, miramar lake and some places around Scripps Ranch and Ranch Penasquitos . I plan on going to Rancho Cuyamaca, anyone been there? I'm trying to find some nice intermediate trails around here that aren't crowded by horses laying landmines everywhere.

 

Mission Trails, like up-hill alley
Martha's Grove in Poway
Sycamore Canyon in Santee off of mast to Martha's Grove
Hollenbeck - Awesome trail. At the end of Otay Lakes rd where it meets the 94.
San Miguel Ranch - Off of East H/Proctor Valley through the hills to Jamacha Road
Sweetwater
Noble Canyon - Another great one.
Daley Ranch in Escondido
Lake Hodges
Just to name a few. Let's ride!

 

Noble canyon if you like to downhill. Not a place for a huffy.. but if you have a decent bike...its aot fun. Bring a friend so that you can shuttle ( park at the top and bottom) The ride down is a sweet time....lots of fun
