Someone used a chain saw to cut out parts of a well-known sign along the Kancamagus Highway letting travelers know that they’re entering or leaving the White Mountain National Forest, officials said. The damaged sign is in Albany. Saws also were used to cut doors on restrooms and other signs along the highway, and there was shotgun damage to some of the interpretative educational panels and kiosk boards in the parking lots, White Mountain National Forest spokesperson Joseph Phillips said. The damage is estimated to be thousands of dollars. Officials believe the sign was vandalized between a week and a half to two weeks ago. “It’s an ongoing investigation,” forest spokesperson Colleen Mainville said Tuesday. “It wasn’t just on the Conway end, it was across and went over to the Lincoln portion of the Kanc, as well. The Conway area was hit the worst.”She added that if members of the public are out and see something damaged or have any information to help with the investigation to let the Forest Service know.
