A whimsical scene created by paint and brushes evolves on the walls of a parking lot on the way to sun-drenched Puerto Escondido in Mexico. A skeleton in a top hat dances beside a cactus wearing a sombrero, while a red fish with one eye swims through a field of yellow circles. Nearby, three tiny red horses trot under a green arch. Is it the Mezcal? Or is it just what you see?
