The next more difficult course is Yellow. The Yellow course generally goes along trails and other linear features, but often has controls on features just off the trail. Now it becomes important to plan a method of finding a control, not just picking which trail to take. Ther times it may simply involve knowing when to look for a small hill or cliff near the trail. In any case, it is important to plan ahead.
Route choice starts to become important.
At this point emphasize routes that provide the most sure way to find a control, rather than the fastest or shortest way. In the diagram above, a compass bearing is being taken from a trail bend to control point 3. Make sure that the direction of travel arrow at the top of the compass is pointing in the direction you want to go, and not in the reverse direction. Leaving that setting alone, turn yourself and the compass and map until the red end of the needle points to the N on the dial. You and the compass and map turn around it.
