Fun in the Snow

I was just looking at some winter trips for my son and me. OMSI has a winter trip to some nice a-frame cabins right when I am looking at going on vacation. Might not night be a bad idea, I think. I will have to look into it more and see if there's a catch. I wanted to give the boy a chance to hang out in a snow cave. This might be an opportunity to do that, while not being too far from a warm room in case he doesn't like sub-zero sleeping conditions.
