Well I love the idea, but around these parts they usually just make it up as they go. A few weeks ago at Lancaster, PA they did have a map, but only one copy (I traced it), and the second half of the course was completely different than the map. So that's where we stand here.
On the other hand, If they set courses up like the ones your showing, I'd have to have a map- They look like some confusing courses, with all those places that get used multiple times. I'd really be in trouble. I'd run out of gas out there going round and round trying to find the end...
Often wrong but never in doubt.
