The San Francisco Amateur Astronomers are sponsoring three upcoming star parties, out at Lands End, San Francisco, part of the "100 Hours of Astronomy" event this week. See The Urban Astronomer Blog (which, BTW will now have a link on our Blog - see to right) for all the details.
As Paul Salazar (TUA) points out, people outside SF can check the "100 Hours" website for events in their area.
