With Halloween being synonymous with spooky or mysterious. My take on a photo challenge this week is this mysterious sunset in Ventura, California. It was a gray evening as California sometimes gets. Right at sunset the sun poked out and had at least 8 different shapes over the course of the sunset. This one was very mysterious taking the shape of a mushroom cloud.
