Tugs can show up at our wharf at any time during the day or night. They wait at our wharf while a load of limestone fills a barge at our local quarry. This night, the captain had not yet turned off the tug's powerful searchlight, which they had turned on at night to safely navigate their way to the wharf. Since it lit up the wharf in such a delightful way, of course, I had to take a photograph.
