This was Difficult!

I saw this guy dusting a field while out driving with my wife. Once I figured out how to get to the field he was at I parked the car and hustled down to where he was swooping down. I was not sure how long he had been there so I was hoping for a shot or two. Once I got there I was treated to a half dozen or so passes. I was close enough to see the piolet and I figure he saw me . I was lucky to not have been sprayed directly. My wife did not like that I went so close to him but I couldn't get the shot if I didn't eh?
