I just got back from So Cal and riding some of their trails that go along the river. To me they seemed pretty cool because suprizingly few people were using them and they almost always avoid having to use the road at road intersections. Do we have anything like that in the Bay Area? The only trail I've ridden has been Iron Horse and it felt like there were too many children, people walking their dogs, etc. to really hammer it on a road bike. Plus with all the stops I may as well ride a country road.
