Just curious about how you carry water on a multi-day tour. After reading some of the last few posts (trailer vs panniers, how much stuff to take, etc), I'm interested in what you have done.

I've been on several multi-day, multi- tours and one thing that frustrates me is the challenge of finding and carring water.

I have front and rear panniers, two bottle bosses + one clamp-on on the down tube (bottom side). I usually start off by buying water in bottles to get the bottle. After that I'll find a grocery store and hit the cheap gallon and refill the bottles.

Sounds easy enough. Right? Man! Water weighs a LOT! Plus, even though I really don't carry that much stuff, the bottles do take up some room.

Next year I have a ride from Salt Lake City, UT to Tempe, AZ through the Grand Canyon. The water thing has been bugging me a little. Just curious on what you do. Thanks for your input!
