Mair Pleasant though it may be to skim stones on Black Moss or live with thieves in Manchester, as described in the poem, I'm not sure that either of those experiences would afford the same opportunities for learning about other people and their cultures, or seeing the great buildings of the world, or viewing great works of art, or seeing breath-taking scenery, that travel does.
Though I suppose living in Manchester might provide most of those. It's a city of great diversity, great art galleries, its own orchestra and concert hall, and industrial and political heritage.
Being brought up near Manchester and going to university there perhaps stimulated my interest in the rest of the world.
