Sidewalk Graffiti Provides Navigational Assistance For Subway Commuters

"A considerate cartographer wielding a stencil and a can of spray paint has left a helpful navigational compass at the top of the stairs outside the NRW train at Prince Street for commuters exiting the station.

The unknown compass crusader stenciled the sidewalk at the uptown 6 train station on Spring Street as well. "
