Genealogy Serendipity Moment - Howell Family in Oregon

Several years ago I was helping a friend research her Howell family ancestors. One day she asked if I would go with her to the Howell family cemetery outside of Salem, Oregon. It was a lovely spring day and it took about an hour to drive to the location of the cemetery. The only problem was we could not find the cemetery. The information was that the cemetery was just down the road from the intersection of Silverton Road NE and Howell Prairie Road NE. This was before the use of GPS and the Internet in general.
