Southeast England - S9.E9

Arcing along the southeast coast of England, we'll travel from Canterbury (with its famous cathedral) to Dover (stoutly fortified from Roman times to the Battle of Britain). Then we'll hike the trails that top the towering chalk cliffs of the South Downs, wander into the beachy resort of Brighton (England's Coney Island), and push on to Portsmouth, whose naval heritage has left it with the best collection of historic sailing ships anywhere.
