Key Clubs from Greenville High School and Foxcroft Academy will join Dexter Regional High School today and Saturday for a 30-hour fast to raise funds to end world hunger. Approximately 40 students, who will be locked inside the Dexter school, will start fasting this afternoon and will end their fast at 5 p.m. Saturday. While at the school, the students will do community service projects such as cleaning classrooms. This is the seventh year the Dexter Key Club has raised funds for hunger relief. The public is invited to stop during the fast and visit with the students.
