I busted my butt shoveling snow for the kids. My boys wanted a rink out back despite skating 3-4 times a week already. This is where I learned to play hockey.
100'x40'. Half the size of regulation. My friggen back is sore.
Good on you. I hope your boys were right there with you with shovels too though, Mac.
In the city, we'd flood parking lots and tennis courts. Voila! Instant rink.
