If you didn't already know, there are two close regional DrupalCamps both on June 26-27 (Sat/Sun). DrupalCamps are basically mini-DrupalCons, so you get good, quality sessions (for both beginners and gurus) and a decent attendance of usually 200-500 people (a lot easier to find someone than the 3000 people at DrupalCon San Francisco).

I attended DrupalCamp Colorado last year and I'd highly recommend going to either of these. Post a comment if you're going to one of these to let your fellow Nebraskans know or if you have a question!

I'll be at DrupalCon Chicago this year since I'll already be in Chicago with an on-site work week for Palantir.net. I'll probably be presenting a session as well.

I will be attending DrupalCamp Colorado for the second year in a row. Last year's attendance was about 300 if I remember right. Attendees ranged from those who had heard the word "Drupal" and knew nothing else to folks like greggles and rszrama who do lots of good community work already.
I don't think I'm ready to present anything yet. Last year was my super newbie time learning what the community was all about and how to interact a little better with it. This year I plan on attending fewer sessions and going to more BOF's etc where more discussion happens as opposed to being talked at.
Hope to see some fellow Nebraskan's there!
