It's not that bad at all, if you can walk on a sidewalk you can walk on this ledge. If you think that's bad, I've seen kids on the summit Mt. Lady Macdonald before. I have seen children on the chains at Mt. Yamnuska.
I agree. What's the point of doing that hike with kids? One slip and your life as you know it is over, because it literally IS your fault for taking them to their final resting place. There are accidents and then there are preventable occurances. Parents who choose to neglect the difference are not good parents and not deserving of the gift of having children.
