Bob and TurboBeaver, excellent points. Thank you.
Every year I enjoy "flying the river", just north of New Holstein, in the evening. Lou has posted a couple of videos which show the beauty of the flight, and Sarah and Jim Dickerson always get some great photos of the river flying sessions. I remember the first year I did this, and I was really new and green to flying behind other aircraft, and I was unfamiliar with the "wash" that came in the air behind the aircraft just in front of me. I will never forget the first time I did this because I hit some air that sent me into an unusual attitude like right now! Scared the dickens out of me and I discussed this with Steve Lewis and Steve Eaton and they pointed out some of the finer points of this type of flying. I was amazed at the amount of turbulence that was created by our super cubs. I learned real quickly that one needs to position to be above or below, to the left or the right, of the aircraft in front of me.
Someone told me this also happened at Johnson Creek on departure, leading to some scary moments.
