OUCH! That sux!!! If three of the top guys all got lost that shows really bad for the promoting club laying out and marking the course. Of course pushing that hard and trying to get a better line that the other guy can get you in trouble.
Thanks for sharing!
Edit: Just went over to the D-37 site looks like it was the amount of virgin trail caused the problem. Props to the club for not racing on the same-o-bland-o.
