A hot, late afternoon sun cleared the streets of this "living ghost town" of almost 400 people. Among the sparse buildings and homes, an adobe wall caught my eye. Ill formed, irregular and easy to overlook, it was invisible until a glint of metal directed my eye to the wall's embellishments. Interesting textures, embedded metal flowers, bugs, birds and everyday items, made this wall a colorful and happy surprise. What was once an ordinary wall is now art, someone's expression of hope in a harsh land.
