A man airlifted from the Blue Ridge Parkway this week falsely reported being bitten by a snake, authorities determined today. “Based on information developed in our investigation, on the scene and speaking to folks, things are not pointing toward snake envenomization,“ said Ridge District Ranger Kurt Speers. Rescuers found a 48-year-old man lying semiconscious in the Dripping Rock area near mile marker 9 on the parkway Tuesday afternoon. A passer-by told authorities the man had been bitten five times by a timber rattler, information later passed on to another man who photographed the victim being airlifted to the University of Virginia.
