Fire Water

There's an old Indian saying:  "The brave who brings with him the most water, will surely be chief of the desert."   
Canteens are for vodka - water belongs in EVIAN aerosol misting cans! 
Pull this trick from your sleeve, Cochise, and you too can be chief of the desert. 

What is essential is not what is necessary. 
It's what is so incredibly UNnecessary that it becomes a must-have. 
Get it?
