DrupalCon Barcelona

See https://assoc.drupal.org/drupalcon/volunteer/onsite. Still have to buy your own ticket :-( I suspect for developers in big Drupal shops they get support from their employers to be there, but for those of us who are freelance or amateurs it is, although good value, a major investment, and the cost has prevented me, and I think many people not employed big wealthy organizations, from going more often.

My first Drupalcon (although it was in my own city) I felt a bit lost and I think the kind of involvement from volunteering would have benefited me as well as the conference.
