This is not your typical vacation photo, but these are often the kind I come home with. I mean, how many pictures of the ocean do you really need? We were out on the balcony of our condo when it happened. The grass on the sandy dunes swayed in the breeze. The continual sound of waves crashing to shore had nearly lulled my husband and I to sleep. Then I saw it. I jumped up, camera in hand, and began to focus on the side of the building next to ours. “Those meters are so cool!” No reaction of surprise. My husband just smiled. He had seen this behavior before.
