‘California Academy of Sciences’ sounds like a professional organization, but it’s actually a museum open to the public. I went over a decade ago but it’s one of the coolest museums I’ve ever been to. They have an indoor, 4 story rainforest greenhouse dome thing filled with plants, free flying birds, and a bunch of other animals. They’ve also got a nice planetarium and natural history exhibits. Their green roof was great when we saw it, it’s just my ideal fantasy solar punk building.

TL;DR: Lots of pics here. Go to the California Academy of Sciences if you’re ever in San Francisco, because it’s at the Golden Gate Park and you’re probably going to want to go there anyway.
