It's pathetic that one member of this forum has to use a thread like this to display his insecurity and neuroses. Like many other members I started taking my son on hikes and ski trips long before he was 10. We climbed the Lions, Harvey and Brunswick together, sometimes in snow, skied Diamond Head and the Harvey traverse and did many serious scrambles in the Rockies. I spent sleepless nights before some of these trips working over every angle, making sure we were prepared in every possible way. Even so there was risk involved, always. Today he's an avid and accomplished climber and skier, far above my standard but I take pride in the grounding I gave him years ago.
Yesterday's conditions were no worse than they are most of the year in our mountains. If hikers in southwestern BC stayed home after rainstorms their window of opportunity would be down to about six weeks a year. Every trail up the mountains from Howe Sound offers tricky sections. You go out equiped and prepared to deal with them. You pay your dues over the years, run some calculated risks, make mistakes and learn from them. But, as yesterday, after all the calculation and preparation things can still go badly wrong.
I spent 20 years in SAR, witnessed the results of mishaps that should never have happened and some where every precaution had been taken but things still went badly wrong. The greatest reward I ever received was meeting a lady we'd airlifted off Bruswick unconscious after a bad accident, years later still climbing, still loving the outdoors.
We should all keep going out and keep taking our kids with us if we can, giving them the benefit of our experience. They'll learn by doing, not by sitting behind a keyboard slanging people and laying claim to knowledge they demonstrably don't have.
