If you are going to see a Red Sox game..
BMX Track that can also be used for RCs
from Longwood Green Line Stop keep walking Left towards Fenway on the Beacon St. side of the trail. Just before the trail ends, you will see the track behind the trees. School children usually occupy the track for bmx bikes, but the track should be free during high school hours 7am to 3 pm Mon - Fri.
