April 26, 27 or 28, 2013.
Each year the California Academy of Sciences sets aside a weekend during which SF residents of specific ZIP codes get in free. Our weekend is the last weekend in April. (To see the schedules for other neighborhoods, look here: http://www.calacademy.org/visit/)
Three questions you will probably ask:
Won't the line to get in be suuuuuuper long? Yes, but it moves fast.
Are there going to be a zillion people there? Yes, but it's not any more crowded than on Nightlife nights (Thursday night programs for ages 21+).
Will there be hundreds of children zooming around without parental supervision? Yes, hundreds of children; no, not without parental supervision. Plus, what's more fun than seeing a kid's wide-eyed excitement about science? They're so cute.
The website announces a new interactive exhibit tracing the evolution of humans. The Aquarium has a replica Phillipine coral reef with thousands of colorful fish. There's also a rain forest exhibit with butterflies, parrots, trees, frogs and other birds. (And a giant spider or two that I avoid like the plague.) Maybe we'll get lucky and get tickets to the (free) planetarium show.
Who's in? I can go Friday or Sunday.
