I had to buy long pants...and a coat!
No surprise there then......
Considerably further north when compared to your part of CA...... little to no history of cross country skiing in CA, whereas the "weegies" are masters...
Take a trip north, I don't know, Stavanger, Tromso, wherever and you'll have to get thermal underwear as well ;D
But have a nice trip. IMO the Norwegians are an excellent bunch, maybe not quite as laid back as the Dutch seem to be, but nevertheless a very good, nice crowd.......
