If you're attending RubyConf in San Francisco, there's a gathering at Zeitgeist on Thursday, the 19th, starting at 9 PM. The venue offers pitchers and plenty of outdoor seating, so attendees are advised to bring a jacket, and it's important to note that it's cash only. For those traveling from the conference, you can take BART to the 16th St. Mission stop and then walk north on Valencia. The event is organized by Chris Wanstrath, known on Twitter as @defunkt.
