I’ve driven through the tunnel on Yerba Buena Island many times, but never stopped to check it out.  When I finally did, I learned there really isn’t that much there except a lot of “No Trespassing” signs and abandoned buildings.  I did find this vantage point in a precarious spot overlooking the Bay Bridge.  It wasn’t easy to hang out there very long, but the view of San Francisco was worth it!
