The day before I left for a seven day camping trip in the Sierras, I told the wife I had to go to REI for some camping supplies, and snuck by the Hiller Museum for a visit of their event called YAK ATTACK! No I didn't pull a fast one on the wife, as instead of packing my truck, I went out the door with my camera gear, but promised not to be gone too long.
Date was August 4th, and yes there were a couple of planes that weren't Yaks. Not sure what else came in after I left. Tried to depart twice, and planes came in, sending me back to the airport.
