Why Hail

Today the weather was very odd because it was raining and then all of a sudden it started to hail. Until it started to hail I was riding Storm. While riding Storm I did some small circles at a trot and making them bend to the inside. I also worked on my side passing both directions and lead departures. It was a good day till it started to hail. That's I got to today, I am hoping that the weather will be nicer tomorrow and that I will be able to work with all three horses!!!
