Actually, it's not wrong at all. The most important part of the code (i.e. item #1) is "Stay in control and avoid hitting others." Item number 2 on the list says, "People ahead have the right of way; it's YOUR (you as in the person farther up hill) responsibility to avoid them. I don't see a single caveat in there that says that it's your responsibility to avoid them unless they happened to have fallen in a spot where you can't see them. Not hitting others implicitly means not bombing over blind spots and running down little girls that happened to be stopped. It's not rocket science.
The item you refer to says you shouldn't stop--it doesn't say you can't fall in a blind spot and it doesn't say anything about others not having any responsibility to avoid you if you stop in a bad place.
So, according to you, there's an explicit rule that prevents little girls from crashing in blind spots and then crying about it. No, there isn't.
Should you take care in stopping where you can be seen? Absolutely. Does that affect an uphill skier's responsibility to avoid crashing into you? Absolutely not.
I can't even believe we're having this debate in light of the fact that a child was killed.
Actually, in Colorado it is part of state law and it doesn't say "shouldn't", it says "MUST not".
It is an important debate BECAUSE a child was killed.
"Hiding" in a blind spot IS dangerous! Darting out from the trees or a crossing trail into a run IS dangerous! Starting across a trail from a stop into the previously "safe" path of an uphill skier IS dangerous!
We need more people realizing that since we all share this space there are things we ALL need to do, and not rely on the skills and attention and good judgement of the uphill skier without also being smart ourselves.
