Nice trip, Russ. Also, I appreciate the review on the Platypus and Dromedary bags- I take out of the way trips sometimes too and I`ve been thinking about shelling out for something like that. FWIW, Ortleib has a line of water bags too, but I`ve never used them either.
My current water carrying method depends on how far between services. Iodine tablets if there are reliable "alternate" water sources, a 2 Gal gas can (never used for gas) if it`s a short span between water sources, a 7 Gal water can (but I`ve never put more than 5 Gal in it) for long spans. You guys went three days on two gallons each? That`s pretty water-efficient, but I think I`ll stick to my two Gal per day system!
