In summertime, many Washingtonians take responsibility and throw it out the window. They surrender to the heat and humidity, pack up the family, and let summer turn Washington into a small, sleepy town. Those who stay behind inherit the town that Newport might be in February. Those who flee inherit the wind, the ocean, the mountains, fresh air and a new style of living at their home away from home.
