When i went up Waynu Picchu (the mountain in "that photo" behind Machu Picchu) i had everything in my bag  - 5/6 lenses, body, cleaning kit, filters, laptop and all the accessories needed to run a download, plus a backup drive. And a change of clothes, bottle of water, and my stopover gear for the night - it was upwards of 12kgs i would assume.  I almost killed myself on that little trek... i got back down and was feeling a bit feverous after the exertion and my legs didnt work properly! (vertical climbs tend to do that) Lesson of the day for a thread which seems to be going in the same direction of "carry everything and anything you might need"... sometimes less is more... or something like that - depends on the shooting circumstances i suppose.  I missed a few good shots when i got back down as i just headed for the door needing to have a drink (water gone) and a seat and maybe something to eat...

In every stone sleeps a crystal.
Remember the Shaman, when he used to say:
Man is the dream of the Dolphin"
