First day with rain but we dodged the showers and drove up to Muir Woods which is a preserved valley of Redwoods.  Nice 2 mile walk.  Drove to Richmond to collect our remaining Walmart items - really depressing Mall with about a third of the shops closed down and a feeling of poverty.  Drove past Saint Quinten prison on the way - why do all the prisons in the SF area have such great views do the harbour?
