OHIOPYLE, Pa. (AP) — Authorities say a man on a whitewater rafting trip was thrown into a western Pennsylvania river and died after his foot apparently became trapped under a rock. Ohiopyle State Park operations manager Ken Bisbee told the Pittsburgh Post-Gazette that the man was part of an eight-member group that had rented two rafts from White Water Adventurers. Bisbee said the county 911 emergency center contacted the park at about 1 p.m. Saturday about an overturned raft on the Youghiogheny River.
