SPECTRUM NEWS VIDEO: The fight over the Constitution Pipeline has died down, but many opponents say the gas companies are replacing it with trucks. Tractor trailers carrying compressed gas drive through small communities to get from fields in Pennsylvania to the Iriquois Pipeline in Herkimer County. The trucks carry highly flammable compressed natural gas and stop twice a day in Vestal, but Town Supervisor John Schaffer says they are safe and pose no threat to the area.
