Me after a shoreline hike at Pt. Reyes collecting floats. The spherical ones are net floats. The cylindrical ones are for crab pots, and are color coded differently for each boat so they know who's are who's. Some of them are quite pretty. They often break loose during winter storms. I've collected about 40 of them over the years.
