I was walking around Shoreline Park at sunset, and there were clouds of all shapes and sizes filling the sky. But, the sun was firmly entrenched behind a bank of clouds that rendered everything a dull gray. Then, the sun descended just a bit, escaped from the grasp of the clouds, and the sky exploded in colors.
