I rallied together and went with about 25 Michigan Hackers to PennApps this past year....what an amazing experience.
Many of the students had never built anything outside of class and almost all of them left the event feeling inspired beyond belief; one of the first-time teams won an award and has since turned their hack into a full-fledged startup here at the TechArb in Ann Arbor!
Great post - will definitely take this into account when planning the hackathons here at Michigan!
