Take the stops with you

Load the 2 stops into your maps app to drive between them.

The file holds 2 waypoints and a stop-by-stop route line. Locations are approximate, often a town center, so use the stop notes to find the exact spot. Your maps app chooses the roads between stops, usually the fastest, so follow the byway signs where they differ. The GPX arrives in a zip file; unzip it and open the .gpx in a GPS or hiking app. The CSV imports into Google My Maps.
