The southeastern corner of Massachusetts is known as the "Old Colony." Its towns, including Plymouth, are some of the earliest settlements in the nation. The restoration of an abandoned railroad connecting the area to Boston has sparked a lively discussion about future development in this region known for its cranberry bogs, pine barrens and farmland. Environmentalists are of two minds on the rail project, seeing it as a way to offset pollution from cars, while they worry about the unwanted growth, or sprawl, the new trains could promote.
