I think filter people are <img src="/forums/images/graemlins/wink.gif" alt="" /> I like hiking with filter loving friends.. I mix my aquamira and lollygag in the sun while they fish out the filter. I then walk to the water source shortly after them with my bag - SCOOOP, dump in the yellow poison - cap it and to lollygag in the sun some more - hopefully my hammock is in view of the water source...pump pump pump pump pump.. I can swing in my hammock.. "Hey it's too bad I have to wait.." pump pump pump pump pump.... "Is there a particular repetitive exercise you do with left hand to build up your strength for that thing?"... pump pump pump pump.. Now usually, after fiddling with the filter, they can come back with carpal tunnel syndrome and celebrate that their water was ready 5 minutes before mine.. They always feel very nice that they can have a drink 5 minutes before I do <img src="/forums/images/graemlins/wink.gif" alt="" />
