Hundreds of thousands of cruise ship passengers head to the small town of Bar Harbor, Maine, from May through August, swamping the quaint streets and infusing local shops with cash.

Residents concerned about air pollution from the ships and the crush of tourists brought forth a ballot initiative two years ago meant to slash the number of visitors to 1,000 a day.
