OH Community Help: How do you stay active during the cold winter months?

I try not to let the seasonal weather affect my exercise routine.  When it comes to running, I'd rather be outside than anywhere.  However, we do have some pretty cold days, and for those I go to the gym and do boot camp or cross boxing, or run on my "dreadmill"........which I HATE but will do when I have to.  I also have a makeshift gym in my basement where I can do P90X and other DVD workouts.
