As the weather changes, joggers, like some exotic species of bird, begin to molt. On frigid winter days, when the wind and snow sweep down from Canada, the joggers wear heavy layers of clothes. Ski masks cover their faces, woolen caps hide their hair, and heavy scarves are wrapped snugly around their necks. Gradually, however, the weather warms, and the bulky layers of clothes are peeled away. First, lightweight jogging suits in terry cloth, velour, and even plastic dot the paths in parks and along streets. As spring changes to summer, winter-pale legs and arms begin to appear, covered only partially by shorts and T-shirts.
