It has been circulating all over the network during the weekend.
We know where World Expo 2017 will take place! After three World Expos in Europe, it was time (as expected) that it was celebrated in America. It will take place in Chicago, U.S.A!
For those who are not familiar with World Expo: the last one took place this summer, in Stresa (Italy), and the next one will be in 2017, because it is an event that takes place every 3 years. Hence the importance!
Are you planning on going? :)
