The farm where Aunt Marian grew up is located very near U.S. Route 15, which is a major north-south highway in Pennsylvania. The intersection near the farm is right before the road starts to ascend the mountains south of Williamsport. (An aside: Williamsport is where the Little League World Series is held each year.)
When I take photos of the Solomon homestead, I’m always surprised how near it is to various commercial establishments that line the highway. It is probably less than half a mile from the farm to a Family Dollar store, a Subway, and a surplus outlet.
According to Joan Wheal Blank in Around Montgomery:
Now known as U.S. Route 15—a major highway that extends from South Carolina north into New York—the section referred locally to as the Montgomery Pike opened in October, 1930. Before the road was improved, tolls were collected at the top of the mountain to fund any repairs or grading that was needed to make the dirt road passable.
