Part of the curb along the median is a red zone. With the red as a background, someone has used silver spray paint to emblazon an important motto for all to see. From across the street, I believe it says "Unions!"
As I pass, and turn my head to look more closely, I discover that it actually says "Onions!"
I can offer no further illumination on this, but thought you would want to know that onions are not being left to fend for themselves in the complex modern world.
