It’s time for the annual East End House Summer Block Party! Tomorrow night at 6:00pm, the party gets started in front of the East End House (105 Spring St.) in East Cambridge. There’s a BBQ, ice cream sundaes, live music, a moon bounce, and much more, and it’s all free.

East End House just wrapped up their backpack collection drive at the Cambridgeside Galleria, but they’re still accepting school supplies at tomorrow night’s event. The idea is to ensure that every East End House student has a backpack full of supplies this fall, and they’re looking for all the stuff you’d expect: pencils, notebooks, calculators, rulers, art supplies—everything kids need to succeed in the classroom.
