In the winter, the tide is low at night. This means that the oyster pickers and clam diggers work through the night, in every kind of weather except lightning storms. Last night we caught up with Dan and Dave at 9 pm on their way out to pick oyster singles. They ended up working until 1 am. Here they are rolling a tub around on the beach. Working on the tideflats at night is cold, and dark, and quiet, save for the sounds of seals, gruntfish, and the occasional car on the highway.
