A tour that exceeded each and every one of our expectations and was a highlight of our visit to San Francisco. The Silicon Valley tour conducted by Fred is a must do if time permits. Fred is one of the most benevolent, amiable, conversational, understanding, and well grounded tour guide anybody could have asked for. His keenness to share the history of the beauty that Silicon Valley commands, had each one of us learning with a renewed curiosity. He caters to the needs of adults and children - there wasn’t a single dull moment on the 4 hour tour - and we can only thank Fred for it. A wonderful experience - worth it through and through! He even checked our interests of activities and ensured that we visit the Computer science (Robotics) and Neuro science blocks at Stanford
