Having a ball at the Roslindale substation

For the second year, members of Roslindale Wants to Play set up a "Build Zone" in Roslindale Square, this time in the old trolley substation at Washington Street and Cummins Highway.

Kids (and adults) enter a large space with lots of cardboard and plastic tubes, platforms, kid-powered ball lifters and basketball-like ball collectors and then just go to town.

The two-day Build Zone will be open tomorrow between 10 a.m. and 2 p.m.
