Yeah, I tried to post to your pop-bottle question and got a message that I was not approved to send there, then realized it was on that GATE format where only the moderator could respond.
What I wanted to add was that we use gallon and larger sized bleach bottles, to store water to take to camp. Clorox, etc. are used to purify water for drinking anyway, so we just make sure we rinse 'em out well and take the labels off. A little chlorine taste just reminds us of the city. But don't make the mistake of drinking the original contents - YUCK!
