A 55-year-old Hood River man was taken to a Portland hospital with serious injuries after the motorcycle he was driving Friday afternoon collided with a van at an intersection on Highway 97 near Wasco.  The Oregon State Police says a van driven by 68-year-old Merva Haley of Wasco was turning off Clark Road onto the southbound lane of Highway 97 when the van was struck by a northbound motorcycle operated by Mark Peters, who was ejected from the motorcycle.  Peters was transported by Sherman County Ambulance to Mid-Columbia Medical Center in The Dalles, and then transferred by LifeFlight to Legacy Emanuel Medical Center in Portland.  He was wearing a protective helmet.  Haley was not injured.  OSP troopers from The Dalles Area Command office are continuing to investigate.
