As the monsoon clouds inch closer to the Old Pueblo, mermaids and other sea folk from long ago begin to stir.
The crashing thunder and pouring rain transform the desert into the world it once was, where mermaids, jellyfish and octopus played and danced in gardens of coral and seaweed.
Some say the mermaids are what makes the passing clouds burst open, as they fall to the creosote scented desert. Others believe they come from a dry underworld only to be awoken by the dampening earth.
But we believe they live among us — only showing their true selves when the streets are glistening and the air is cool.
In any case, each year in mid-August, when the monsoons are in full swing, the mermaids reach the surface with merriment and glee, dancing in the rains and parading through town.
People cannot resist their beauty and siren's call to dress up, dance and join the mer-party.
