Yes, I think there are paths near the bay next to the airport which is close enough to my neighborhood to regularly go to, but most paths are more like narrow running paths and you do have to watch out for many joggers along the way. It doesn't help if you want to really put your head down to so some fast "motoring" miles. You might end up with a dangerous situation if you do. I've heard of other bike paths in other parts of the bay, but I really want to go to a place that I do not have to transport my bike in a car to get to. We had it really good in Milwaukee where our rides start right at our front doors. It all comes down to just the very high volume of motorvehicles in California makes that hard to happen in most urban areas over here.
