The reason the US Nationals in Oshkosh are not being promoted (or on the EAA Calendar of Events) is because it's not a public spectator event. Events on our calendar are designed to promote activities that our members can either participate in or watch. The IAC U.S. National Championships are neither. That's not to say people couldn't stand at Wittman Regional Airport and watch, but the event itself is not designed for spectators.
