As a kid growing up in Minnesota, I spent more than a few chilly afternoons bundled up in layers and sent outdoors to go sledding, skiing or skating when the temp stayed in the single digits. My mom was very inventive and she knew how to dress us properly for practically any winter condition--including lining our not-so-waterproof snow boots with plastic bread bags. Even though it must have been a pain to get us ready to venture out, now I know why my mom didn't want us to stay in the house. She knew we would have more fun outside. Of course, there were also many winter days when even my mom thought it was too cold to play outside. That's when the kids in the neighborhood gathered at the houses of friends and played indoors. My favorite house to visit had a play room stocked with a million Legos. The play area stayed super toasty right next to the furnace room. We even took our socks off. On those wintry days walking barefoot in our cozy Lego land, my friends and I almost forgot it was winter.
