The Bubblegum Alley is a 70-feet/20 meters long alley in San Luis Obispo, California, the walls of which are covered with chewing gum.

It is thought that the gum sticking tradition started around the 50s and continues to this day.

Despite numerous cleaning attempts, some areas of the brick wall are thought to have remained completely covered with gum since the 60s.

This place is awesome and I’ll definitely try to visit it someday.
