Number one priority by far!!! I'm thinking more of an emergency preparednesss situation. Hell... there's still about ten thousand homes in NEPA without power since last Friday's storm. What are you guys doing? I'm trying to mix it up. Usually have several cases of bottled water that the kids use for sports, etc anyway so the stock gets rotated. Have a few of the Aqua-Tainer containers. Then a few of the micron filters and finally there is the damn pool in the backyard I figure I can use.
