Tucson gets very little rain and has very few storm sewers. It does have many dry creek beds, which are called “washes”. As the wash goes under a road, there is a tunnel. Many of these tunnels are used by people as homes and also a place for artists and other to meet. At the entrance of these concrete tunnels and often for the length of the tunnel there is graffiti art. Some is good, some not so good.
