I moved to Massachusetts in the 70’s after graduating high school and lived in the Backbay section of Boston for two years. I loved all the lights, city life, the nightlife, variety of buildings and Boston’s rich history.
One of things I learned was the poem for why the color of the lights changed on top of the old John Hancock Building:Steady blue, clear view. Flashing blue, clouds due. Steady red, rain ahead. Flashing red, snow instead.
Today the light is a steady red meaning rain ahead just in case the dark skies weren’t a big clue.
