SImon makes a pioneering trip across the Rainbow Bridge, which connects Canada with the the newly opened USA. Mick, meanwhile journeys to the hilly county of Dorset and scales its mightiest peak, risking family unity on the way. We compare notes and tensions.  With thanks to Steph, Silas and Aruja for taking part. The recording of pheasants comes courtesy of http://www.freesound.org/people/klankbeeld/
