Braving ice and snow requires specialty equipment: snowshoes for walking, snow tires for driving, and flamethrowers for gently freeing pets from snowdrifts. Prime your wintertime gear with today's Groupon: for $15, you get a four-point snowboard tuning (a $30 value) at Community Skate and Snow, located in Arvada.

The family at Community Skate and Snow readies boards to bomb peaks with four-point tune-ups executed amid a trove of specialized equipment. To begin, the shop's Wintersteiger grinding machine smoothes board bases into a level plane. Then, a wax tech deploys a p-tex drip candle to fill in gouges caused by exposed rocks and troll claws. Dull edges are honed sharp enough to carve into a sheer cliff or slice clean arcs into fresh snowfall. A final coat of wax slicks the sole runner, protecting it from damage and minimizing friction so boarders can whip through frosty air and escape its bitter, icy raspberries.
