Some local "know it all" comes by to check out my plane. "Why did you do it this way? I would have done this or I would have done that." Darn idiot is giving me advice on a plane that he is a few years from even thinking about.

I would like to tell them to build a plane just like it, fly it at over 100mph and try and keep track of it. Land it in one piece, then come talk to me.
