You have done this many times actually, like when Adam built and flew his prop jet. I am not talking about sitting around a table talking though. I am talking about either going to them, or having them come to you, and then showcasing different aspects of the hobby. You could visit a control line speed racing event, or invite someone over who flies ornithopters. Visit a scale masters competition, or invite some competition sailplane pilots to come fly at your field. Visit an indoor flying event, like microfilm, penny planes, and peanut scale, etc, or invite some control line combat flyers to come mix it up at your field. There is a massive amount of interesting content in the world. You don't have to create it all yourself.
