Four Square Court Locations
Danehy Park, North Cambridge
I just heard from someone who lives in the area that Danehy Park has some courts. Freshly painted, but a little below standard. Probably 8' courts, not the league size of 16'. Worth a try if you live in that area.
Which brings to mind, you all have the number for your city councillors, right? You should call them and mention that you want more four square courts permanently painted in your parks.
