A North Platte man has been sentenced to a year in jail for being drunk when he drove his lawn mower on a city street on his way to a liquor store. North Platte television station KNOP-TV reports that Donald Wymer was sentenced Tuesday in a Lincoln County court to 365 days in the county jail for a third-offense drunken driving conviction. The 51-year-old Wymer's driver's license also was suspended for 15 years, and he was ordered to pay a $600 fine. Police say an officer saw Wymer drive to liquor store on his riding lawn mower. After he left the liquor store, a Nebraska State Patrol trooper stopped him in a residential neighborhood, where he failed a field sobriety test.
