Big Omaha is a conference that started in 2009, and has become a place where innovators, entrepreneurs, and creatives could call home. If you want your life to change, attend this conference. The good news is that this year there are three locations and times to choose from (Kansas City, Omaha, and Des Moines). If you can't afford the event itself, the free pre and post parties are definitely worth the price.
(If you are a student/nonprofit, there may be a discount, but I didn't tell you ;).
