I hate how they barely mention porters in the article. They are THE essential piece of the trip, and many expeditions have failed because of problems with porters.

Another thing they failed to mention that is interesting is the piss bottle. It's the bottle you paint a skull and crossbones on and pee in at night in your tent when you don't want to freeze your elbow off doing your business outside. Erik Weihenmayer (blind guy who climbed Everest) once drank out of one by accident, and his partner joked "Can't you see the label?"
