Just lay out the mat in your backyard, "flood" it with a couple inches of water -- and, voila, you've got your own 37 foot hockey rink. We're not hockey players at Burbia. We can't see the puck on TV, and we can barely see it when we're on the ice. But we do think this is a blast. Lace up the skates and start flying down the ice . . . mostly on your butt. So, wear padding; and look forward to all the good stuff -- après-skate. Hot cider, Irish coffee and luxuriant hours in the hot tub.
