This weekend, the quarterly US #editathon takes place in 10 US cities - read all about it on the OpenStreetMap US blog.

The #editathons are not just a great excuse to meet up with other OpenStreetMappers to push on projects, but also an opportunity to learn more about OpenStreetMap.

Read up on the Mapbox blog on how to find the Mapbox garage. Here’s a photo from last year’s event there:
