The driver of a 2012 Harley Davidson was airlifted to Stony Brook University Hospital Monday evening after losing control of the motorcycle. Town Police Capt. Chris Anderson described the incident Tuesday. The cycle was headed west on Route 27 in Montauk, he said, approaching the intersection of South Fox Street near Shadmoor. “A deer ran onto the roadway,” the captain said. “He tried to avoid the animal and lost control.” He was rushed to the East Hampton airport, where a helicopter took him to the hospital.
