Family movies along the Charles
Hatch Shell, Charles River Esplanade, Boston
The first film of the Massachusetts Department of Conservation and Recreation and WBZ NewsRadio 1030-sponsored “Free Friday Flicks” series, “Daddy Day Care,” starts at sunset. Bring your blanket and get a good seat under the stars at this riverside spot best known for the annual July 4th concert extravaganza. Which reminds us — the series will take a break over the 4th of July weekend, then pick back up July 15 with “Megamind.”
