Save your two liter soda bottles full of tap water with about three drops of bleach in them.
I think I had five hundred of them when we were getting ready for Y2K.
But that’s just me.
Heh!
Yah...I don’t have five hundred. That’s my problem...
I usually have about three jugs filled with water, and then if there’s a storm coming, I fill as many buckets as I can find, in case I need flushing or washing water. But I’ve been slacking off, I guess.
