This reminds me of a story on the radio some years back about how the Park Service was considering charging people for the cost of rescuing them. I remember this was in the Pacific Northwest, don't remember if it was Washington or Oregon. They interviewed a park ranger who related a story about a guy that went hiking above the tree line, by himself, and a storm moved in and the temperature dropped. They had to go up there in the storm and haul his butt down off the mountain. He sort of re-enacted his conversation with the hiker and it was pretty funny (though I'm sure he didn't intend it to be).

ranger: So, did you have a map and compass?
hiker: No.
ranger: Did you pack some warm clothing?
hiker: No.
ranger: Did you have any means of starting a fire?
hiker: No.
ranger: Did you bring anything with you to help you in case you got lost or the weather changed?
hiker: Well... I brought my cellphone.
ranger: Arrrrgggggg...
