How long can a camel go?

how long without water? well depends ..To know that you ll have to get the current temperature variations in the given desert then the length of the desert and breadth then you ll need the type of sand if soft or rough...then the number of quick sand spots and number of dunes ..NEXT you ll need the Type of camel and its age and hoof diameter and limb length...next you ll need the weiught of the rider and age and skill level...LAST BUT NOT LEAST youll need to know the number of tribes youll come accross and the probability of you running into a gay tribe !!!!
