The entire Southwest has abandoned adobe buildings, and especially houses, all over. At one time the mud construction was very practical here in the desert. But, adobe requires a lot of maintenance. It made sense when people lived on and worked the land, but for people going to jobs elsewhere, adobe maintenance simply is not worth the time, effort, and expense.
