I've read many opinions from hikers regarding how they treat their water, but I don't recall seeing anything about the quantity of water folks tend to carry. As this could (depending on quantity) represent the heaviest item in my pack, careful planning would eliminate unneccessary weight. I don't like carrying my platypus bladder in the hydration sleeve since I never know what I have left. I like the idea of cameling-up when possible and carrying less (perhaps 1 - 2L in the bladder and a Gatorade bottle in a side pocket). Obviously, quantities would tend to vary where seasonal trends might render some sources unreliable. Any thoughts?
