Still) BALD HEAD ISLAND — A week after the Bald Head Transportation Authority met and a majority approved moving forward with purchasing the island’s ferry system for $47 million, the island’s political leaders drafted a letter to the state treasurer, opposing the sale as it currently stands. The authority is mandated by legislation to purchase the system, owned by Bald Head Island Limited LLC. Though there’s no deadline baked into the law that created the authority for this purpose, trustees have been working at this for three years — last week’s move to apply for revenue bond approval marked its most significant step yet.
