Somebody planned to climb Mount Massive in Colorado’s Collegiate Mountain Range. They discovered the Highland Trail was not the correct way to the summit and left a note (graffiti) for their hiking companion to save them the experience of repeating their mistake.

What wrong turns have you made? How do you share your trail knowledge with others? What mistakes are worth leaving for others to encounter on their own, and which require notification in your judgment?

How might we point out what is worth noting and not be a constant flashing amber light of ‘caution everywhere?’
