Adults Only at Cal Academy of Science

I've been to the Academy of Sciences at least 10 times already (I've got three kids!) and every time I go, I say to myself "I've got to get back here without the kids one day." Well, now I can and not only without my kids, but without ANY kids there at all.
Now through October 2009, Thursday evenings the Academy are for the 21 and over crowd. Music, booze, food and "provocative science" (those are the academy's words!). 6pm-10pm
It's $10 to get in ($8 if you are a member). Keep in mind that regular admission is something like $24.95 for adults, so its a real bargain.
