The town is “thinking pink” this month, with many residents participating in the town’s third official observance of October as Breast Cancer Awareness Month. Spotlights have turned the usually white Town Hall temporarily pink. Selectman Jerry Lawrence, an early supporter of the initiative, said town employees have been encouraged to wear pink each Friday. Pink ribbons are available at Town Hall; they are free but residents are encouraged to make a donation. “Thank God, no one close to my family has been hit by’’ breast cancer, Lawrence said. “It’s one of those situations where you don’t want to someday say, ‘I wish I had done more.’ We just want people to know there’s support for them here.” Businesses are getting into the act. The Sandi Rose Café on Route 106 is offering pink pancakes this month in a fund-raising effort.
