Another bank vault? Looks like these things were built to endure all kinds of intrusion (including time itself).

You don’t think there’s any cool, refreshing drinks inside the rusty old Nye and Ormsby county bank vault so you just press onward. Looks like there’s a tower of some kind nearby and a ruined old building on the cliffside.

Your thirst is getting overwhelming, though… so you can also just leave the town altogether; maybe you’ll have better chances of finding water outside this old canyon?
