A motorcyclist was struck by a falling tree Saturday afternoon while operating a dirt bike on Kim Hill Road in Roulette Township. The Roulette Chemical Engine’s Facebook page says the man was found un-responsive and taken to UPMC Cole before being transported to UPMC Altoona for treatment of his injuries. Firefighters say the falling tree struck the man, who had just attended a memorial service for his father, knocking him from his bike.
