It also meant coming up with creative ways to maintain the ice.
"We built a rink every year," Kassian said. "We used to get out there with our shovels and clean it every night and then we'd even drill little holes so some water would surface to kind of re-flood itself."
Kassian said they used a regular drill with a thicker, longer bit to drill deep enough into the ice each night that the pressure would force water up onto the surface and ensure a smooth sheet the next morning, effectively acting like Mother Nature's Zamboni.
"It took care of itself overnight," Kassian said.
