Special Olympics Maine says an estimated 400 people are expected to take part in its annual Lobster Dip fund-raising ocean plunge on New Year’s Day. The Lobster Dip was Maine’s original cold-water fund-raiser when it began in 1988 with about 15 participants. It is now the largest such fund-raising event in the state. Last year it raised nearly $100,000 for Special Olympics Maine’s sports training and athletic competitions serving more than 3,500 athletes with intellectual disabilities.
