Chicago dyes its river green and has done so since 1962 when sewer workers used green dye to check for sewer discharges and had the idea to turn the river green for Saint Patrick's Day.
This live feed is in Chicago for the St Patrick's Day celebrations
Originally 100 pounds of vegetable dye was used to turn the river green for a whole week but now only forty pounds of dye is used and the colour only lasts for several hours. The dyeing can be best viewed from the East side of the Michigan Avenue bridge, the West side of the Columbus Drive bridge or upper and lower Wacker Drive between Michigan Avenue and Columbus Drive.
Following this, the St Patrick's Day parade starts at Balbo and Columbus. The parade units will proceed north on Columbus Drive and the viewing stand will be located in front of Buckingham Fountain.
Little is known of Patrick's early life, though it is known that he was born in Roman Britain in the 4th century, into a wealthy Romano-British family. His father and grandfather were deacons in the Church. At the age of sixteen, he was kidnapped by Irish raiders and taken captive to Ireland as a slave. It is believed he was held somewhere on the west coast of Ireland, possibly Mayo, but the exact location is unknown. According to his Confession, he was told by God in a dream to flee from captivity to the coast, where he would board a ship and return to Britain. Upon returning, he quickly joined the Church in Auxerre in Gaul and studied to be a priest.
