Good points, greendoctor. I will say I am not properly set up for this in terms of AI nozzles. I expected to hear about your truck mounted boom in this thread. That is a great story from what I remember of it a few years ago. And, yes, I meant the vaporization and moving of ester products moreso than drift. We have been warned that these things can show up 5 miles away. There are hundreds of thousands of dollars in crops between all my sites and five miles a way!
