Join us tonight at Laughing Man Tavern to talk urbanism and earthquakes at the latest Greater Greater Washington Happy Hour!

We’ll be downstairs from 6-8 pm. Laughing Man will offer happy hour drink specials and selected appetizers for $4.

Laughing Man is at 1306 G Street NW, near the 13th Street entrance to Metro Center station.

Also, Greater Greater Washington and the Mobility Lab are inviting technologists and designers interested in re-inventing transit information tools to participate a hack day on September 10th.

Bring your projects or ideas to share, or join up with others and collaborate on building tools to improve transportation around the DC region.

In addition to providing a space to collaborate and learn, staff from area transportation providers will be on hand to answer your questions about transit data and opportunities for collaboration with third-party developers. A schedule of presentations will be announced prior to the event.

The session will run from 10 am to 5 pm, followed by drinks nearby, at the Mobility Lab, 1501 Wilson Blvd in Arlington (near the Rosslyn Metro, DC Circulator, many other buses and more).
