In my neck of the Southeast Wisconsin woods we experienced overcast skies, with occasional dense cloud cover; and even some rain. Whenever any sort of break in the clouds occurred I exposed a few frames. During peak (85%) coverage saw nothing but gray clouds and dim daylight. No magic darkness. No slivers of sun. Or crescent shadows and highlights through the trees. Still… some memories.
