The smell of the air on a cold, crisp night. Especially if there are stars out.

The sound of snow underfoot -- fresh snow, not sludge.

Getting to pull out all my woolly sweaters and long heavy coats and scarves (see, it's okay to knit myself twenty million of them!) and wear lots of dark jewel tones.

The sight of bare trees with every twig coated in ice and glittering like something fairy-spun of crystal.

Seeing my breath rising in white clouds.
