SF Moms & Dads take note — there’s a Children’s Art Center at Fort Mason in the Marina & they offer a great range of art classes for kids as teeny as 2 — sculpture, painting & drawing, photography & mixed media — I want to sign up!  Looks like they have drop-in classes for $20 so it’s relatively low committment too.  Maybe it’s the artist in me, but sounds like a great way to spend an afternoon, so just passing it along.
