sidewalk

As long as people are acutely aware of it, it's not a problem, right?

Either they ran out of hexagons, or color blindness has a nasty cousin called "shape blindness."

Please use sidewalk on the wesouth side of the street.

You know those games of baseball that all the kids played in the street, and they had to yell "car" every time a car was coming? Yeah, it's kind of like that.
