The automatic airport doors opened only to drape me in the cold biting air. It had snowed only a week ago and the temperature was 30 below normal. But I was meeting my husband after spending two whole months with my in-laws. So, the stinging cold changed to warmth the moment we met. Well, actually the warmth I realized came from the car’s heating system, which, to my surprise, can be left running for as long as one wants to keep the passengers warm. Conserving energy? What is that all about? This is America.
