For those of you using Garmin Basecamp or another route planning tool
you can create a file of the waypoints from Google Maps by following these steps
1. click the '3 dots' next to Waypoints and select the option to 'Export to KML/KMZ'
2. choose 'Export as KML' and save the file
In Basecamp, you can use the File -> Import function to load the waypoints to a list.
If you're using another app,
free free to email some brief instructions or the function to use to wpc20xx@gmail.com
& I'll add them here.
