What are some winter activities you are looking forward to doing with your LO's? Can be indoor or outdoor.

We had a very uneventful/long winter last year, and it became rough towards the end, for all of us. I want to come up with a list of ideas of things we can do to cure the winter blues. I'm not a fan of driving in the winter if it's really snowy, so some ideas that are at home are best. Of course, would love some ideas of things we could do as a family if it's a decent weekend, weather wise.
