Heathrow Intl - London UK:
Picture yourself in a tube-shaped train that travels both above and below ground. Capitalize the "T" to call it "Tube". Ride the Tube to Buckingham Palace, Westminster Abby, Picadilly and see Trafalger's Square all lit up for Christmas!
London is just like a British San Francisco draped in and older facade with different looking automobiles (and traffic directions) and nearly everyone speaking with a "bloke"-like ring off their tongues. It is quite exciting and comfortable and the people seem to be more considerate and tactful than urban Americans. Thumbs up to the UK!
