It is our experience that the boarded hockey rinks are, by far, the most used rinks. Therefore, they are the top priority. Other rinks, depending on their location and previous usage, will be worked on as time and personnel permits. Skaters tell us where they like to skate by leaving their skate marks on the ice. When staff gets to the rinks at 5 or 6 am, they can tell if someone or a lot of people were skating the night before. This evidence leads to our prioritization.
