Thought of this in the shower after commenting on a post about securing boot partitions.
I’m not knocking on any of these things, only noting their similarity. When taken to the extreme, all of them seem to evoke a weird mix of paranoia and eager anticipation.
Water purification is a big problem, however water does not need to be treated to fulfill the standards for normal drinking water here, boiling collected rain water should be plenty good enough at the start.
Further up in the mountain we have soo many freshwater springs that most hikers don’t pack water as it is just dead weight.
Down here by the coast, fresh water springs does exist, but are way fewer.
