Each DrupalCon is filled with inspiration, networking, and fun — and while cutting-edge sessions are plentiful, sprints are the heart of the conference. A sprint is a get-together for focused work on a project, and a fantastic opportunity to make contributions to Drupal.
Even if you are not giving a session or leading a BoF ("birds of a feather" event) at DrupalCon, there is plenty of opportunity to give back and make a difference when you attend the sprints. There will be extended sprints taking place between 19-27 September, but the main sprint day is Friday 25 September.
