The San Diego CityBeat has a “beer club” that hosts events at local bars on the first Wednesday of each month. If you’re a “member” you get one free craft beer. You have to sign up for it by entering a (last quote-marks, I promise) “contest” through their Web site.
Past events have been held at the Tap Room and Hamilton’s. The next event is July 2 and you have to register by June 27. They e-mail you the location before the event. It’s like a rave, but for dorks.
