The day is nearly done and I just noticed the date. It is the anniversary of the Triangle Shirtwaist Factory Fire. 146 workers were killed after being locked in at their sweatshop. 123 of them were women. Some were teenagers.
ETA: This project CHALK commemorates the victims every year by writing their names on the sidewalk outside their former homes. You can also read this interesting blog post about the project and the fire HERE.
