Our neighbors gave us tickets to this place almost a year ago and we finally had a chance to take a trip there on the Sunday before we left to Denver.  The weather was nice that walking in through the Golden Gate Park was perfect.  The museum was large and there were a lot of things to look at.  We watched a solar system film which was interesting.  We liked the jungle exhibit and the aquarium.  We were tired by the time we walked back to the car to drive home.  This was a nice place and totally worth a day trip up to the city.  The boys were also very happy with the souvenirs they bought themselves.
