A water purifier is a good investment. These are good ones and can be taken with ya. Once you have it you can use lake water, pond water, and river water. Endless supply as long as you can keep the filters clean. It's easy with the Berkey's. I own a "Berkey Light".

As you can clearly see, the top is the pond water and the bottom is the purified water reservoir(sp?). wink

"In the beginning of a change the patriot is a scarce man, and brave, and hated and scorned. When his cause succeeds, the timid join him, for then it costs nothing to be a patriot". Mark Twain - 1904
