Do yourself a favor: Today is the California Academy of Sciences Free Day. Emphasis on day -- perfect for the funderemployed, who more than anyone deserve a day of brain-melting beauty. So ditch the gray pounding and run-run-run pace of the city, in favor of the 4-story rainforest exhibit, to take just one awesome example. Here, you can see a frog so beautiful it might confuse you, because it's just sitting there, with no glass or anything between you and it, and you can see its little lungs going, and it's just sitting there, it's fine. Not only that but sometimes, if you're lucky or calm, a full-on butterfly may land on you. A butterfly, we're saying, a soft bright special one, may land right on you, and then no one can stop you from believing that the butterfly landing on you is a sign of your pure heart and secret nobility. Don't even get us started on the way bat rays can make you feel, when you actually stop to think about the fact that they're flying -- flying -- underwater. Flapping their wings. Go look at them; you'll feel better. For free.
