When I went to those great cities I saw wonders I had never seen in Ireland. But when I came back to Ireland I found all the wonders there waiting for me. You see they had been there all the time; but my eyes had never been opened to them. I did not know what my own house was like, because I had never been outside it.
(Bernard Shaw "John Bull's Other Island")

"Wandering's the most addictive drug there is, I think, and every hidden road leads on to a dozen more."
