Tod: at least with my Garmin, the easiest way to set up a route is build it
as a chain in which using the bearing and distance from the last previously
defined waypoint. This only requires scaling from the distance scale and
using the compass rose. When you follow the route and get to each waypoint,
you can update it to match the GPS-estimated position there, thus
continuously updating your route.
