Having a proper GPS is no sure thing either if you don't know how to use it or pay attention. Just ask
@Sidewalk .
I was at the cooler when he climbed up the hill and turned the wrong direction down the road. I called him back and sent him the right way, but rather than turn onto Boy Scout he went around the corner and climbed the road for a while.
I heard there were a few other wrong turns as well.
Not sure if it was that same year or the following one but he was in a sprint finish with Carl and missed the turn to the Yodeller at the end. Carl backed off and let him go the wrong way, then took the right turn and the win.
