The annual Lost Nation Air Show is the July 11th, 12th, and 13th.
This year, for the first time, there will be a demonstration of control line flying.
I have flown at Lost Nation several times, and the Airport Manager is a good friend of mine. He has flown control line and is a motorbike rider.
If you're in the area, support would be cool....
The airport also owns several adjacent soccer fields and there is a good chance that a contest site may evolve if the demonstration is successful.
Have fun!
