Father-and-son duo Dick and James Strawbridge head up the River Helford on the latest leg of their Cornish tour. In Port Navas they feed the locals at a soup kitchen with a difference, and forage for fungi with expert Justin Whitehouse before David Gear shows Dick how to get creative with his selection of mushrooms. Plus, James gets a scare from a creature he encounters on a fishing trip with Simon and Linda Filmer.
