I spoke at the Awesome Inc. Mobile miniConference in Lexington, KY over the weekend with Jake Behrens. About 100 people showed up for the event. I think its awesome that that many people have an interest in iPhone development in Lexington, KY. I did three sessions. My my two technical ones ("Scrolling Like Butter" and "Web Services with Cocoa") didn't have too many attenders, but "How I Made an App that Has Over a Million Users" seemed to be a hit.
