Weather Whither

This week's question for Write Brainers and Write Brainer Readers is...

What with winter currently upon us (subzero temps and windchill and all), do you find that you're writing substantially more, or less, due to the season? Does winter cause you to head in and hole up with your pencil? Or does winter bring on a bout of cabin fever that cuts into your creativity? If winter's not your thing, do you have a particular favorite season for writing?

(OK, so that was more than one question. Call it a question "cluster" if you will. Anyway. Discuss.)
