me with two Canon Elan 7N's (with grips) and 300mm f/4L IS + 1.4x tc (on hand) and 70-200 f/4L on the shoulder, before i tried out my home-made lens camo http://www.yaphoto.com/fm/camo_me.jpg
I hiked the inka trail a year or so back, and have a llama photo in wikipedia taken from that exact same spot(the weather was not quite so nice, however).
