I was sitting in my backyard at 5:00 yesterday afternoon and there was 1 or 2 UND planes coming over about every 10 minutes. They practice touch and goes at the Mayville airport almost daily and their loop takes them over my house. Maybe one of those?
I know last year Brad S. had regular reports from the informal workouts in the summer. This year including up to this point in September, except for the Weatherby debacle, there's been nothing. Is everyone under a gag order or what?
