A Sherman man is facing a DWI charge after he was seen driving erratically in Sherman on Thursday. State Police in Jamestown responded to a witness report of an erratically driving vehicle, and they found 41-year-old Ryan Pratt on Hazen Road after he had already left the roadway. Troopers say Pratt failed several field sobriety tests and later registered a blood alcohol content of .15%, nearly twice the legal limit. He was issued tickets for Sherman Town Court and released.
