He had to clear the rinks in the middle of the night at first because he didn't want to get into trouble about liability etc. He just wanted his girls to have a place to play hockey and it seemed a shame not to use the pond that was right there. Finally someone waited in the dark to find out who was clearing and flooding. It makes a lot of people very happy.
