Volunteers raising money for a new playground at the Hugh Cole School got some help this week from a tiny source: Eight-year-old Brielle Reese DeCastro, 8, a third grader at the school and the daughter of Cheryl and Tony DeCastro. Brielle spent the winter shoveling snow out of her grandparents’ driveway, doing odd jobs and soliciting donations for the playground at her mom’s hair salon and White Tiger Karate, where she takes classes. As of this week Brielle had raised $150 for the project, and she handed over a check on Monday. Now in its third phase, the playground will cost about $65,000 and fund-raisers have about $5,000 to go. The third and final phase, to install the last parts of the playground, is scheduled for late June.
