Brett,
Hockey is my absolute favorite sport to play.....It happens to be my least favorite sport to watch though. We set up lights and play after dark.

I have a pond set up this year that is 4 feet deep, oval shaped the size of a hockey rink and the edges are lined with railroad ties. Also i can raise and lower the water level instantly if needed to make better ice! We will be playing lots of hockey (until I brake a bone or two at least)
