This week Ben Fogle is recalculating the height of England's highest mountain Scafell Pike with the team from the Ordnance Survey; Liz Bonnin is at Cheshire's Lyme Park to witness one of Autumn's greatest natural wonders- the Red Deer Rut; and chef Gino De Campo is in his adopted home county of Hertfordshire to find some woodland ingredients for his mushroom bruschetta.
