Early morning dog walk in Tower Grove Park. At 15º F it was pretty chilly, but I bundled up pretty well and was warm the whole time.
A good trick I figured out for taking long exposure pictures in the snow is to take a glove, put it on the snow and rest the camera on it. This protects the camera from direct contact with the snow and also gives a handy solid base to get a steady shot.
Some more good shots:
