While out on our boat one day, a pod of dolphins showed up unexpectedly in our wake. The faster we went, the larger the waves. The larger the waves, the more dolphins! First there was one, then two, within a few minutes there were two different pods, one flanking the starboard side, one the port. It was so exciting and exhilarating to watch how close they came to our boat and the swift speed in which they moved.
