A St. Patty's Day Tradition

For my out of town family, and people such as myself that live here but have not previously taken the time to figure it out, here is a brief explanation of the beginnings of the green Chicago river tradition:

The tradition started in 1962, when city pollution-control workers used dyes to trace illegal sewage discharges and realized that the green dye might provide a unique way to celebrate the holiday. That year, they released 100 pounds of green vegetable dye into the river - enough to keep it green for a week!

Today, in order to minimize environmental damage, only forty pounds of dye are used, making the river green for only several hours. Although Chicago historians claim their city 's idea for a river of green was original, some Savannah natives believe the idea originated in their town.

They point out that 1961, Savannah mayor Tom Woolley had plans for a green river, but due to rough water on March 17, the experiment didn 't work and Savannah never attempted to dye its river again.

And to finish it off, a couple nice pictures of the river in all its green glory.
