[pct-l] aquamira quantities

[Brian Erickson]

Hey Folks,
  I'm a new addition to the list and apologize if this question has already
come up. I've always used Aquamira as water treatment and plan to use it on
the trail. However, I have never purchased it for such a long hike. I know
you are supposed to get 15-30 gallons per 3.5 oz pack of liquid drops. Any
thoughts on how many boxes of the stuff that translates to for the whole
trail? Thanks.

Pura vida
Brian
