The Friends of the Historic Columbia River Highway’s Antique Car Tour to celebrate the 100th anniversary of the highway will take place on Saturday.  The tour will begin in Troutdale and go to Vista House, Multnomah Falls, Cascade Locks, Hood River, and Mosier before finishing at the Columbia Gorge Discovery Center in The Dalles.  The organization’s Jeanette Kloos says they have a diverse group of vehicles making the trip.  The cars will be parked on the Cascade Locks Marine Park lawn during a lunch stop, and Kloos recommended the lawn outside the Hood River Library to view the vehicles on the move.  The tour wraps up at the Discovery Center at about 4 p.m. Saturday afternoon with a meet and greet event.
