Bubble Gum Alley

Bubble Gum Alley - San Luis Obispo Bubble Gum Alley is located in San Luis Obispo, California. It can be found in the downtown of this town that's located near the coast, halfway between Los Angeles and San Francisco. Both sides of the alley are covered with chewed bubblegum. A shop at the entrance to Bubble Gum Alley has a gum machine where you can get your own contribution to the wall (or bring your own chewed gum with you). The gum started appearing on the walls in 1960. People complained in the start but the gum kept on coming and now its a piece of art worth seeing.
