this am i got ready to aviate, just putting my helmet on when VROOOOOOM. a cropduster whipped accross me, 50ft up , spraying some white cloudy stuff right alongside my dirt road (runway). he sprayed back and forth (affording me his skilfull avoidance of wires etc at twice my speed!) for most of the morning. i'm awful glad i hadn't taken off a few minutes earlier, we wouldn't have hit but he's working, i'm playing, so i'll come back manana.
