DS is planning to start taking Metro home from school (from DC to VA) some days due to a change in my work location so I can no longer drive him some days. He can take it right after school (board at about 3:45 PM), or do study hall and take it as late as about 5:30 PM. He'd prefer it not to be like sardines. Understanding it just will be like that sometimes on the orange line, does anyone know whether crowds tend to lighten or worsen after 5PM?
