21F, frosty! But, nice mountain views (clear enough to see the snow blowing off the top). Today, wore same as yesterday (fullfinger gloves, tights, longsleeve shirt under coat), but also a short sleeve shirt under the long sleeve one. My 12 yr old wore a bandana over her mouth/nose. 15 yr old has a balaclava and ski mask but didn't see him leave so don't know if he used either.
