Hey I heard back from the San Francisco zoo on their group rates, which are the following:
Adults (18-64) - $9.00
Youths (12-17) - $4.50
Seniors (65 and up) - $4.50
and if there happens to be a kid under twelve attending, their admission will be $2.50.
If you've got Sketchcrawl shirts, wear 'em... or maybe cover yourself with Sketchcrawl stickers, so that we look like the legitimate group that we are (the zoo lady on the phone sounded kind of suspicious)
Looking forward to seeing all you guys... and the animals!
2danimator - the zoo has parking lots, at $5.00 for the whole day. Not too bad and I'm pretty sure there'll be room at 11 am. There are also parking lot kind of things along the Great Highway, next to the beaches(?). I'm not sure if those have charges, but it's maybe an option.
