I can't resist
I've been to the summit in pouring rain and high winds, then hiked back down. The wet lichen on the rocks was worse than ice, you can't wear crampons on rocks. In retrospect, I probably shouldn't have gone. I took some nasty tumbles. Could have easily broken something. I was alone, probably another dumb thing. As was mentioned before,how much more time is added out there in the rain and wind if something goes wrong. Is everyone in trouble now from the cold and wet? If I had anyone with me, we'd have turned around at treeline.
I just think the #1 rule is: the summit is only half the journey, you have to get yourself back out. Getting to the top to reach a train, or coach or whatever should not be a goal. Getting back down by your own power, intact should be the goal, of any climb. I don't give a damn if there are other options if "You just make the summit." Pushing on to reach the train wasn't smart. Getting himself and the people he was responsible for down and out of that situation, that would have been smart.
Once, going up the Jewell Trail we got soaked minutes from the summit on the Trinity Heights Connector. I immediately opened my pack and put on my raingear, my wife refused, opting to reach the safety of the summit building. She was soaked, we took the Cog down. It was never the plan, but the thought of hiking down the Ammo in the rain freaked her. It saved our *****, but I would never plan a trip with that in mind. Generally, I won't carry my wallet, so I purposely could not have the option anyway. On this day, my wife had hers, so we lucked out.
So, maybe it wasn't this guys plan to take the Cog down. Maybe it just saved his ass, but it seems to me he had ample time to rethink things and turn around. Being a tenth of a mile from the summit and being 5 or 6/10ths, as they were when it started raining on Lion Head, is a big difference in the rain and wind. If he's alone and wants to go for it, fine. If he's got kids in tow, well, I don't think he had the right to endanger them. They're only kids, they don't know. And as was said before, now they have this false sense of,"We can make it through anything." because their dumb luck got them through this time.
I think they took an unnecessary risk, pushing on.
