Never escape your home--and never teach your children to do the same--to escape the climate, whether it is too hot or too cold. You will only associate a warm home with a cold, faraway place or a cold home with a warm, faraway place, so that the next time the climate becomes extreme you will salivate like a Pavlovian dog and yearn to leave your home again.

Invest your money in a heating system or a cooling system. That way your house will be a pleasure to live in no matter what the climate is.
