That is cool, Funked. I just would be pissed as hell right now if it were me. This damn sure isn't a 'mini-con' in terms of the work you and the other organizers have put into it. Arranging hotels, lining up guest speakers, getting a location and caterers for a banquet, creating a website, arranging networking and internet access for attendees, etc... And I am sure there is more that I am not even thinking of.
Like Nash said, people are always gung ho until its time to come out of pocket. I hope you pull it off, but I have a feeling that by the time its all over, it would have been cheaper for you to go to Indy.
