Tomorrow is a great day in many parts of the world where Irish people live because they celebrate Saint Patrick's Day, the patron of the Irish country. They celebrate it everywhere wearing their flag's colours, especially the green one, wearing their traditional shamrocks and many other things. In Chicago, USA, where one of the greatest celebrations takes place, they have a parade, they choose a queen and they even dye their river in green for that day!!!, you can see it in the video.
Do you know the name of the river?
