A fund-raiser that began as a way to help Scituate families whose houses burned down in the December 2010 Nor’easter has become a tradition. The Third Annual Great Scituate Scavenger Hunt, hosted by the group 12 Women Care, takes place on Saturday, with money going to the charity of the winning team’s choice. Already, 23 teams have signed up for the contest, in which each team tries to complete a list of challenges, each with different point values. According to Katina Bentley, who started the event, “It was received so well, people had so much fun doing it, that we wanted to carry it on as a tradition.” She added: “Even if you don’t win, the money goes to a great cause. People walk away and say it’s one of the [most fun] days they had.” For more information, visit www.12womencare.com.
