Drupalcon is great fun (I'm sure), and (as importantly) a fabulous opportunity for the Drupal community to share, to learn, and to advance together.
I love Drupalcons. But I have never been to one.
How can that be?
Unlike many in the Drupal community, I do not get paid to "do Drupal".
I "do Drupal" because I enjoy the interactions with the community, seeing the work I do get appreciated and used, and to "scratch my own itch" for the websites I build.
