I have been to PWA at least 3 times a month and every time I am there I see this twin Piper that isn't listed on flightaware. I think it's either a Navajo or Cheyenne. Any way today, 9/30/06, after leaving for the Alva airshow the tires were aired up but it an another Cherokee had graffiti all over them. I have been asking and asking and no one knows. If you could give me some info, i would appreciate it.
