On a similar note, I remember a post here on the ETS forums that discussed one Ultra-light Hiker's article where he mentioned that he didn't carry a FAK because they weighed too much and because other hikers on the trail would have one.

I don't know if this and other weight saving ideas are commonplace among the ultra-light hiker community, but it burns my bacon to think that they're putting the onus on others because extra weight will affect the expediency of their trip.

I bet stopping to help them would affect the enjoyment of my trip, and yet I'd still do it.
