You should notice that a course line now
appears on the map showing the way to your
destination. If you want to return to your pre-
sent position after attaining that destination
you have two options:
You can mark your present position now
and and save it as a waypoint,
You can use the TracBack feature at the
end of this exercise to retrace your path by
observing all waypoints on the route in
reverse order.
For now just mark your position as a waypoint.
Identify your present position as "HOME"
and enter that name into the name field on the
Mark Waypoint page.
