A Cold, Cold, Cold month

So we have not seen temps above 0 degrees in over a month, the thermometer has hung consistently below -15 most of the time and closer to -25. We have seen -40 at our house and -55 in town. I love Fairbanks and put up with the winter for the summer months of endless light and mild temperatures. I am not complaining just explaining the situation. So, what do you do with two energetic kids when you can't take them out for exercise? You must get creative. Braving the cold to go swimming, trips to Playland, short trips outside where you spend more time getting them dressed then they are actually outside, taking them to a friends house where they run laps around the hallway, trips out to school to run in the gym( Dad needs more exercise also) and any reasonable excuse to get them out of the house.
