I'm in the San Francisco Bay Area, so winter is more like the rainy season than winter (I've lived in North Dakota [4 years] and Pennsylvania [~20 years], so I know what winter can be like).

We'll add some fleeces to our change of clothes in the van, along with waterproof windbreakers, and that's about it. Nights in the summer are cool enough for long pants and shoes, so we have them in the van already.

We've live here since '94 - never been below freezing, no snow shovels, no cat litter/gravel, no chains, no ice scrapers. My winter coat is a windbreaker with no lining.

(When we get to summer prep, I'll tell you we've lived here since '94 with no air conditioning, but that's for another season. :->)
