From the Instructables site:
After an indefinite hiatus, Instructables Build Night returns! Starting June 19th we will be holding bi-monthly build nights at our brand spanking new San Francisco location.
For the first meeting, bring whatever it is that you’re working on, would like to work on or are thinking about working on! If you’re not working on anything, bring yourself, and you can work on your social skills by interacting with some of the Bay Area’s finest makers and shakers!
We look forward to seeing you!
