With a deadline looming this week for the public to weigh in on gas drilling in New York State, the antifracking movement itself has become divided over what its goal should be: securing the nation’s toughest regulations, or winning an outright ban?....... “When we started out, what we wanted was more information on what this means for New York,” said Wes Gillingham, program director for Catskill Mountainkeeper, one of the first groups to focus on the issue. “No one had any thought about calling for a ban. But the more you find out about gas drilling and how it’s been practiced by the industry today, the more you realize it can’t be done safely. It would just be a disaster for New York State."
