Volunteers, some rather chilly, raised over $7,000 for Chebeague Island’s teen programs over the weekend of Jan. 18-19. A Rock-A-Thon went for 12 hours, and the much-anticipated Polar Plunge drew 10 participants. The water temperature was 33 degrees, and at least two hardy souls, Island Institute Fellow Leah McDonald and staff member Chris Cash, went in twice.
