California Academy of Science Museum  12-17-08
This museum just opened a few months ago in Golden Gate Park.  It has 5 main areas; Aquarium,  Rain forest, Natural History Museum, Planetarium and Living Roof.  The 3rd Wednesday of every month is free.  Normally the entry fee is $25.  We didn’t get to go to the digital planetarium.  Not quick enough to make a reservation
