Amen!
Incidentally, that's one more illustration of a sad fact I've often noted: you can be as prepared as Hell, and end up getting killed because of the vast number of totally unprepared people out there who will die unless you help them.
I am not, by the way, advocating for a selfish "every man for himself" ideology. However, I am mentioning that the unprepared can REALLY put a wrench in the works for you. I can't tell you how many times I've lugged a gallon of water on a hike where the group leaders told everybody that they'd only need a quart, and I ended up with uncomfortably little water because the others in the group completely ran out because a quart apiece was not enough.
