Last winter was heaven for local winter sports enthusiasts. And this season has been off to a great start, with unusually cold and snowy conditions providing ample opportunities for skiing, snowboarding, sledding, snowball fights, snowmen and assorted backcountry adventures. We’re celebrating today, Dec. 21 – the first official day of winter – by culling together some of our favorite photos and videos from the last couple years of snowy escapades.
