snowboarding !
Yes you do a lot more moving around while snowboarding, and that keeps you Much warmer then standing still. I'm still guessing with wind chills it should be a good 20-30 F Warmer down at the rally then say riding up chair 10 at Kirkwood. snowboarding on a day that's NASTY I generally only wear long johns, snow pants, a long sleeve shirt, my ski jacket shell, helmet + neck warmer. and even then i generally end up over heating.
I'll just bring excessive clothes and if I'm suprized that its as cold or colder then snowboarding i'll be ready. and if i'm right that snowboarding is colder, i'll have a pile of extra clothes next to me .
