I do both road and mountain riding. My friend and I like to frequent trails down south, like Bernal Rd, Stevens Creek Park, Los Gatos Trail, and a couple others I can't remember. I like to ride on the road wherever I need to go, like having lunch w/ my gf I ride from San Mateo to Palo Alto via Canada Rd. I also like to do weekend trips in SF from Pac Bell Park to the Golden Gate Bridge. And again, Stevens Creek res up to the top via Foothill I think.
What about you? We should meet up sometime and ride.
