As millions of children return for the new school year, Sunil Dasgupta talks with Casey Anderson, chair of the Montgomery County Planning Board, and Eli Glazier, the lead author of a new Pedestrian Master Plan, about walking and biking to school. Only 12 percent of MCPS students walk to school. The rest are driven, ride the bus, or drive themselves. Anderson and Glazier propose improving the situation with better school site planning, design, and infrastructure development. Music by Montgomery County climate band, The Sunshiners.
