Travelling is really like entering new doors - a new country, city, town or village. We step through a door to new experiences, opening our minds and hearts to new places. Huge doors, tiny doors, old doors, new doors, elaborate doors and modest doors. Some of our special doors open into the homes of our home exchange houses, into hotels, sometimes into palaces, castles, grand homes, galleries and museums and, often, just a small or humble house seen on our wanderings. Closed doors are intriguing. We often wonder just what lies inside.
