 A man suffered serious life-threatening injuries in a motorcycle crash in West Fargo last night. That happened in the 3400 block of Cheyenne Street just before 930. The state patrol says the 33-year-old Fargo man drove over the median curb, entered a grassy area, and then sideswiped a light pole. He was thrown from his bike and eventually taken to Sanford for treatment. The crash remains under investigation.
