Mattanawcook Academy Holds Polar Dip 

High school students in Lincoln are going all in to help others.Tuesday, students and staff from Mattanawcook Academy plunged into the cold waters of Mattanawcook Lake, located right behind the high school.The cost was $5 to take a dip.The funds go directly to the Maine chapter of the American Red Cross for Hurricane Sandy relief. School District RSU 67 has been raising money since the hurricane hit through bake sales and other fund raisers.Last week, the Ella Burr Elementary School raised nearly $400 just through students collecting spare change.
