Umbrellas, raincoats and galoshes were the accessories of choice for Chautauquans this week, as heavy showers turned the brick walk into a river and routine walks to the Amphitheater and Hall of Philosophy into quick dashes to avoid the raindrops and puddles. Instead of dampening spirits at the close of Chautauqua’s 2018 season, the rain left beauty in its wake as a fitting farewell to the summer: Those who ventured out into the storms were rewarded with stunning views of the sun shining through the clouds, and rainbows spanning the skies over the grounds.
