I enjoyed the day as well. Operators showed much desire to get it right on most all fronts, much appreciated.
Food for thought, coordinate the water truck and dozer. When water is applied to a hard pack area just track it in with the dozer. You could pick an area or two each time the water truck is out, knowing that time is an issue during watering. That will make a much better experience for the riders and most likely less accidents as well.
