Welcome to Lime Ridge and the east bay. I've ridden with your dad a couple of times. Cool guy.
Thanks. soooo.... where's the good stuff? This was all tame lame fire road, even on my flatbar cross bike. Actually, the singletrack down in Lime Ridge wasn't bad at all.
For a good quick loop, try this http://app.strava.com/activities/27792054
There is also Shell Ridge but you'll have to find the right time of day if you know what I'm saying.
thanks, I'll check those out
