Oh! This reminds me... anyone here heard of the LifeStraw? I know it cannot be bought retail yet, but I was thinking if we pool enough resources we could get it wholesale.. any opinions? and if you've never heard of it look here http://www.vestergaard-frandsen.com/lifestraw.htm I believe the capacity is 100 gallons per straw, give or take. Any suggestions? I've seen them for sale on Ebay, but I don't trust Ebay sellers that much
