"P.S. 6 month old water is really only palatable when it's cold."
A. There's nothing wrong with it, it's just flat. Pour from one container to another several times (creating lots of bubbles), and you probably wouldn't know the difference.
B. We have good, tested community well water here. When I empty a bottle, I ... wait for it... REFILL IT, and put it in my storage area.
C. When emptied, dry it and put the cap back on. When high winds are forecast, just pull out the empties and fill them.
It isn't the winds, it isn't the warnings, it isn't the lack of bottled water, it's the inability of many people to line up all three of their brain cells and think for five seconds.
