Why? It is because I have left the city. I've left Galway and seen cities that are infinitely larger than Galway - namely Cork and Dublin. I'm reasonably savvy at navigating both with and without a map and enjoyed discovering that latter fact. I have also gone to Longford and indeed other counties and had a wander around. I still rely on the position of the sun to tell what direction I'm in - maybe I should ask a friend who knows scouting where the North Star is.
Ireland is shrinking - I need somewhere else to.
