I will be in San Jose next week for two days on my own while DH is in meetings. I will have a rental car, and friends who have visited the area suggest driving to the coast, visiting the Monterrey aquarium, and strolling the boardwalk at Santa Cruz. I really wanted to tour the iconic Silicon Valley companies, but I see that tours are not offered. I also thought about exploring the town of San Jos, but there isn't much info in the CA guidebooks I have, so I need suggestions -- I like historical sites and quaint, locally- owned shops. I also love bookstores, the older and more eccentri, the better (Shakespeare & Co. In Paris is my favorite in the world, to give a comparison). I am slightly concerned about the potential traffic issues in the area, so I welcome any advice in that area, too.
