Today's tip regards the amateur GPS mapping of the American Discovery Trail (ADT).  When creating a GPS line for the ADT in Google My Maps, it easier to do if you import a state's GPX data. Then creating walking directions, if it's urban/ suburban, only route that track for about 40 ADT miles (require more corrections in less distance). The rural's could go as high 90. In either case, the walking, or cycling directions in My Maps start off as Point A to Point B. But you can add directions up to "J" (and you probably should). After that, you can reroute the track about 15 additional times.
