That's not idiocy, that's Bullshit. I appreciate the right of the individual to not get involved, but that doesn't mean that you shouldn't.
To me, an armchair critic is someone who has no real knowledge of the activity and only theorizes about the situations that can occur. Look at the millions of fantasy footbal players out there. Maybe they played some high school ball, but they've never taken a hit from a pro linebacker.
Rockfall on the scale that MisterE is talking about is very uncommon and will defintiely wipe you out helmet or not. I would be more worried about the more common softball size rock rattling down the gulley. You know, the kind of rockfall that the helmet can protect you from.
But hey, If y'all want to keep up your self-righteous attitudes, I'm sure what I have to say won't stop you.
Wait a sec, if that's true, then I guess most of us can't theorize what we'd do if we drove by someone who is injured.
And, I would have to assume that you have, indeed, been in a major rockfall.
I am not sure if this is what you intended to say with this post, but the logic follows...
