Resident protest against care facility
National Children's Center is a adult day care facility for the profoundly disabled. It's located a couple blocks from where I live, and doesn't seem to cause any problems. Like many of these kinds of facilities, apparently there are management and personnel issues, including legal judgments made against the institution.
This person has convinced a few households around the site to post signs similar to the website and postcards that are posted in coffee shops and other places.
Those households, probably because of their interactions with the organization-site (granted, they do own a house on Rittenhouse Street NW that has probably been vacant for at least one decade), are amenable to his pleas.
