We travel because, no matter how comfortable we are at home, there's a part of us that wants - that needs - to see new vistas, take new tours, obtain new traveler's checks, buy new souvenirs, order new entrees, introduce new bacteria into our intestinal tracts, learn new words for "transfusion," and have all the other travel adventures that make us want to french-kiss our doormats when we finally get home.
