Of course Zambonies cannot go out onto a lake, so clearing the snow away from the pond ice requires man power, and really big shovels. Oh, and you have to get up early, too, before the hockey players get there.
Probably the best part of playing hockey on a lake is you get to see some amazing sunrises and sunsets. Hopefully, you are not playing in below zero temps!
