For whatever reason I thought I already mentioned this here, but apparently not. For the last six months or so I've been subscribed to the Bay Area Events syndication feed. If you live in the San Francisco Bay Area I strongly encourage you to take a look at the site. Every Friday it lays out the goings-on in the Bay Area for that weekend. It first lists the events that are going on all weekend and then lists those activities that are taking place on a particular day. Next to each listed event is a "$$$" label (if it isn't free), a short description, and/or a link to the relevant site. It's a great resource.
