A multitude of children, preteens, teens, parents and grandparents passing through the glass doors each day at the Blue Valley Recreation Activity Center on 151st Street. They’re headed to the pools, gymnastics room, dance studio or one of several classrooms. Some come for their one-hour activity, or three-hour camp, or open swim, or lesson. The bustle never stops.
