I agree on getting outside. Winter is miserable if you try to stay inside all the time. It's a hell of a lot of fun if you get out in it.
I love taking the kids to the sledding hill. All the other parents are camped at the top drinking coffee and huddling around a fire, not looking too happy. I'm stepping around the wussy high schoolers who are scared to go down the steep hill, and bombing down head first on a little plastic sled, then running back up for more!
I miss being in Michigan's UP where there was enough snow to really have fun, and lots of groomed cross country ski trails. I used to spend 4 or 5 hours a week on the trails.
