Gotta say that is a pretty telling pic Flatfootin, probably never would have been noticeable without a really prominent outbreak of this crud.   Air might have to tighten their A-B line up and make a few extra passes.    Also.... some farmers ain't gonna be happy if they watch air without the wheels/skids in the tassels, because they don't understand that's not ideal.   

Gotta also say, I'm not totally convinced that a Hagie with the machine bending corn over in the middle and the end of the sticks 20 feet in the air is as superior of a pattern as some want to claim either.   And that's how the corn on both sides of my driveway that I look at every day got done this time, with my brother in the seat.   Maybe I need to climb the silo and see how it looks, though stuff has changed so fast in a week it might not be worth any effort now.
