When we took the nieces and nephews to Death Valley for some adventures, I always had to carry 2 gallons of water (plastic milk jugs), in addition to the water everyone carried for themselves (2 liters).snow camping doesn't really do it for me, but pre-caching water and doing a loop or an out and back in the desert is fkn radical
For every hike, I'd stash one at the half way mark and then with the other, would top up everyone's supply when it was time to turn around.
Then I'd say something like, "Ration what you have, we don't know if some animal or jerk hiker got into our back-up supply." The look on their faces was.....well, this is why I joke about me being on my deathbed asking for a drink from one of the nieces/nephews....ooo, the payback is coming.
By the way, the cache was never molested and all nieces and nephews stayed within normal bounds of hydration as far as anyone can prove in a court of law.
