At least in the pacific northwest there's so much good backroads and USFS land and camping at undeveloped sites or abandonded campgrounds (woot!!!!) with river water or streams coming down from the forests, and not a tap for miles around. last time you passed a tap was yesterday afternoon.


as an alternate to iodine or a filter, I field tested a MSR/MIOX portable sterilizer when it was still a DARPA project, it was pretty cool. water tasted great.
