Vacations are fun, shining sun - or none. This scan is from years ago, the sky a blue-gray hue. Not a storm, just an oceanic fog settling on the nearly empty beach we see now at Tisha's Looking at the Sky. It was a fine day, the gray not allowing the finer treats of the beach to get lost in that fog; the briny sea air, the humid breezes, the foamy surf and the coarse New England beach sand - all here to admire. The climate near the sea is apt to change without warning, from bright to drab in an instant. But beauty in the sky, from sun to a rugged gray is always to savor.
