From a blogger’s account of helicoptering to the Fox Glacier in New Zealand:

John kept wishing for bad weather to liven up our hike, looking forward to being stranded on the glacier and hoping the guides would have to break out the rescue equipment they keep cached up on the ice. I, on the other hand, glanced at our troop of twelve tourists and sized up the lone slice of plastic-wrapped carrot cake our guide was carrying… clearly, being stranded overnight would not have been a pleasant experience.

There are times when a helicopter nearby comes in handy, only more so when hanging around on frozen mountainsides.
