I recently travelled through Chicago en route to San Francisco. The airport was large, busy and a little overwhelming but I had the good fortune of walking from one concourse to another via this pedestrian tunnel. I loved its futuristic design so grabbed a few quick shots as I rushed to catch my connecting flight.
The other wonderful thing was the music - soft, soothing, new agey - occasionally interrupted by a pleasant voice telling me to watch my step as I approached the end of a moving walkway.
It all seemed designed to make me forget - for a few minutes at least - that I was travelling through one of America's biggest, busiest airports.
