Agree: # of deaths, # of rescues. Also, elevation signs along the way. It would give someone an "oh shit" moment without being too pushy. If they've used up half their water and only climbed 2,000 feet...good time to turn around. If they think they're halfway, then they would probably keep going. Actually signs with an elevation profile and marking "you are here" and marking the museum at the beginning and the tram at the end would really bring the point across.
While the hiking club signs might be distracting, I'm thankful for all the work they did. The trails have greatly improved. I'm guessing they were unable to get permission to work on the museum trail.
