Friday is dressed for action in a royal blue flex-o-thane(tm) waterproof boilersuit, belted tight at the waist to show off her lovely figure, and wellies, and action she gets as she throws herself right into the tidal river mud on the banks of the Severn, beneath the remains of a long-ruined pier. The light is perfect as she kneels, sits, rolls, slides, and completely covers herself in thick brown clay.
