Evening at Misquamicut Beach. More people than usual, a beach spread with families and friends and a few spirited swimmers in the still icy water.  Sandwiches, cold chicken, green beans and tomatoes in Italian dressing for dinner as the light dimmed across the water. We read in our big green beach chairs, sometimes stopping to talk or take in the view of the evening coming slowly on. A family in front of us -- mom, dad, a 3-year-old, and a roly-poly, smiling baby -- showed the spirit of the summer beach as they sat before the swishing, incoming surf.
