My daughter had been raised in a rural area with water from our well. If there was no electricity to run the pumps, there was no running water in the house. She never made the connection that this was a "mountain thing" until she went to UCLA. There was a power outage on campus, and she remarked, "Oh darn, I wanted to take a shower".
