I'm in the Bay area and while we do get weather, it's usually just really windy rainy days like today. I will ride on my trainer indoors, but I usually ride indoors even in the summer in the morning as I like an hour workout at 5AM. The rest of the time I'll ride outside.

I also like to use the winter to cross train - especially with weights - so I do more concentrate weight work. And this year I absolutely have to drop 20 pounds. So, I'll use this time to do that, too. Hopefully.
