But I would not think. I will make three pre-determined and will go to a visional center between it. When I will see in waypoint manager what distance for each waypoint is equal to required after some driving correction I will give to rest for legs and will pick up a shovel to hand.
A similar algorithm I had used when I drove with GPS 72 and paper roads map. I love GPS very much from this time.

P.S. That is interesting. When I was obliged to play to soldier we have a equipments what have a worth about a million for the solution of similar problems as in this thread!
