Olly Smith and his puppy Busby take an autumn walk along Hampshire's beautiful chalk stream river, the Itchen. The pair enjoy some of the many diversions and adventures the river offers, including wild swimming, fly-fishing and otter-spotting. They are joined by the Roamability ramblers on their mobility scooters for an accessible stretch of the riverbank and visit the oldest working watermill in the country that King Alfred himself would recognise. They learn about watercress farming and catch a steam train on the Watercress Line to a local brewery to try some of Hampshire's unique watercress ale. Show less
