Why not do something on the "Golden Age of Air Racing"
Are you talking like pylon racing or like the old timey cross-country stuff? I was hoping to get them interested in the latter, kinda like the movie Planes and taking place at Edgewater. With a whole golf course they could easily have several locations to take-off and land.
If you mean something else, please elaborate a little. I really like the idea of race styles other than the standard Red Bull air races (I like those too, but they've been done).
