So this winter is my first playing the great game of ice hockey! My town has a few ponds that no one seems to care about so I've been skating on them and it's been a real blast. Can't believe I've never done it before. The ice is getting pretty crummy. This is a really amateur question but what's the best way to go about refreshing the ice? I read somehwere a hole in the center and a pump to flood it? The pond I mainly use is roughly 40'X100' Thanks and happy holidays!
