World expo 2010, under the theme "Better city, better life" covered more than 5 sq.km. and was represented by more than 200 countries. According to Wikipedia, more than 73 million visitors passed through during the 6 month span and set a record attendance for a single day: 1.03 million people! A world expo is a trip around the world in itself. Like being in a museum 8 hours a day for three non-stop days, my senses were stimulated by hours of continuous impetus from which I needed a vacation afterwards! My favourite pavilion was probably England's "Hairy ball".
