Once again, FTers to the rescue! Thank you all for your guidance.
I found a couple of sites where I can get a small car for $25 for the day, ($12 for the car, the rest taxes and charges) and will go that route.
The Tech museum looks interesting to me, so I'll give that a shot too. I did not realize Moffet Field offered anything for tourists; so will probably try that one too, or Hakone.
All of this hinges on Mother Nature wishing me her best. We have a winter storm supposed to hit tomorrow, so I may not be able to get to the airport on Saturday morning. One inch of snow can paralyze the area - they are predicting three.
Thanks again for all your help!
Bob
