How does /out/ get their water?
>Pump Filter
>Gravity Filter
>Tablets
>Ultraviolet pen
>Boil it

I'm kinda new to all of this and the number of methods and options is kinda overwhelming. I'm curious what the most popular methods are for drinking water in the back country.

Before someone says they drink untreated water; I live in Montana and we have water filtration public service announcements because so many people get parasites from what they thought was safe to drink water, so fuck off with that noise.

Also, What sort of canteen does everyone use?
