Yet it is so hard to find unpolluted water.  I'm sure filtering rain water would not be too bad.  I have heard too much water can leach the body of minerals.  Too little could cause the build up of minerals, hence listening to your body.  I have found mineral water to be much more quenching, like perrier or pellegrino. Too bad its expensive.  As far as getting water in food, raw meat, fruit, and milk is great.

Anybody know of any good websites for pasture raised meats?  Eggs?
