In June I took the family to the California Institute of Science and History. It is located in Golden Gate State Park, San Fransisco. This was a great place to visit, I would highly recomend going if you get the chance. We spent half the day and didn't quite see everything, (kids were kind of warn out) I could see spending all day there with a more patient group.
It has a reef that is 25' deep, and I believe 212,000 gal, three story rainforest in a glass sphere, Amazon exibit, plus lots more. There is a cafe, many shops, planetarium w/shows etc.
Pics do not do this place justice. If you have questions just ask.
I hope you enjoy the pics.
