I've always thought that if course lines need to cross in order to best use the terrain for orienteering, there should be special care to avoid confusion with similar looking numbers. 6 and 9 are super easy to confuse. I guess it is all part of the game, but not my favorite part of the game :)
Eheh, thanks Ross. I finally know how to call my disease: "orienteering dyslexia"! Well, it feels also good to know I might not be the only one with this trouble in this World. ; ) Enjoy Lucia-OL tomorrow!
I also have had the experience of confusing 8 with itself, turning my map upside down and wondering why things looked so strange all of a sudden.
