...And Not a drop to Drink

...And Not a drop to Drink is a challenge in Fallout: New Vegas.

Requirements

 * The player receives the Camel of the Mojave perk, improving hydration by +15% when consuming bottled water.

Behind the scenes

 * The challenge is named after the following passage from the Rime of the Ancient Mariner by Samuel Taylor Coleridge:

"Water, water, everywhere, and all the boards did shrink; Water, water, everywhere, nor any drop to drink."
