You are all welcome to carry a water filter, but until someone can actually FIND any evidence of water contaminated enough to make you sick, then that filter is about as useful as the T-shirt and charcoal.
Just for clarification(unintentional pun!) I do not believe that a certain amount of folks filter their water because they are fearful of giardia, (which is extremely unlikely in the Whitney Zone, or most of the high sierra trails). Rather, it sounds like Mike, Lynne, and others just may not like pulp in their orange juice (I can still see my mother straining my juice because I was convinced that pulp was some sort of contamination)
To each his own, but I gotta say that comparing a filter
to a rock hammer???? is really funny.
