Michael Portillo begins in the ruinous gardens at Aberglasney House near Llandeilo before riding shotgun in the driver's cab on one of the most scenic routes in Britain. Over the border in Leominster, Herefordshire, he steps out onto the dance floor at the Lion Hotel Ballroom, where a grand ball was held to celebrate the opening of the Ludlow to Hereford railway, and finishes this leg of his journey at a traditional cider house in Hereford.
