The closing of the Pottstown YMCA is a story that goes beyond this Montgomery County town of 22,000 people. It is a tale that resonates in every community where affluence is favored over need, and aging buildings are abandoned to add more concrete to suburban sprawl. The local Y, situated within walking distance of both North End and central Pottstown neighborhoods, is across the street from the Pottstown High School campus, its child care facilities convenient to parents, and its pool, exercise areas and meeting rooms readily available to youth.
