What I have been thinking about is how I was able to travel the distance of my ancestors lives in a matter of hours. My Scots-Irish family migrated south through the Shenandoah Valley from western Pennsylvania to Tennessee over several generations. One morning I woke in Lexington, VA and visited the Rockbridge County Courthouse. I saw the original marriage bond for my 4th great-grandparents, John Stephenson and Elizabeth Cloyd. That afternoon, after driving south on I-81, I visited their graves at the Salem Cemetery in Washington County, TN. I stayed in Jonesborough, where Elizabeth started a school for girls in 1820.
I remember traveling through Virginia before the interstate was built, before cars had air conditioners, when a hotel swimming pool was rare. It took a full day longer. The roads were curvier (I consumed large quantities of dramamine on those trips), narrower, and far more difficult to drive. From today's perspective it was a difficult trip.
I try to imagine John and Elizabeth traveling down to Tennessee in 1808. They surely traveled the same route I did - the Great Warriors Trail. I wonder if there were ghosts on their road, as there have been on mine.
