Self-confessed map addict Mike Parker concludes his exploration of modern cartography.

The most powerful maps aren't found on paper or a computer screen.

They're the maps we hold in our memories and imaginations.

Mike Parker visits a primary school in his home town to compare the pupils' maps with his own, drawn from childhood recollection.

And he takes a trip to Ambridge, home of 成人快手 Radio 4's The Archers, to meet Eddie Grundy and ask him for directions around the village.
