Thanks Bill! That's very reassuring!

So are all of your collapsible bottles used for untreated water and then something else for potable water? Great tip by the way.
Do you ever use alcohol stoves, or do you exclusively use wood fires?
Do you have an idea of how much you collect per day if you have to dry camp, including water for cooking, cleaning, and other extras?
Do you filter and boil water for cleaning?
Plus, have you ever tried to store a used filter, or do you stick with Brita's one month recommendation?
Sorry about bombarding you with so many questions, but it's cool to hear from someone with practical experience on this method.
