You're at the ODR. You brought 2 pucks with you to mess around with and practice your shooting, since it's 9pm and you've got the place to yourself. 10 minutes in, and you've already wired two shots right off the crossbar and out of play, in the abyss of snow surrounding the rink. What are you going to do now, practice your crossovers? Make sure this doesn't happen - buy a ten pack of pucks.
