Bar Harbor voters back tougher restrictions on cruise ships
Bar Harbor residents voted Tuesday to place tighter regulations on the cruise ship industry after years of complaints about overcrowding in the tourist mecca.
Voters passed a petition restricting the number of cruise ship passengers who can come ashore on any given day. The town will now allow no more than 1,000 people per day to disembark from cruise ships, though questions remain about enforcement.
