Eeeew is right! I went down that alley once, many years ago! Once was enough!
Bubblegum Alley is a tourist attraction in downtown San Luis Obispo, California, known for its accumulation of used bubble gum on the walls of an alley. It is a 15-foot (4.6 m) high and 70-foot (21 m) long alley lined with chewed gum left by passers-by. It covers a stretch of 20 meters in the 700 block of Higuera Street in downtown San Luis Obispo.
According to the San Luis Obispo Chamber of Commerce and Downtown Business Improvement Association, said it's "a little sketchy".[3] Some historians believe that the tradition of the alley started after World War II as a San Luis Obispo High School graduating class event.[4] Others believe it started in the late 1950s, as the rivalry between San Luis Obispo High School and California Polytechnic State University (Cal Poly) students.[3] By the 1970s, Bubblegum Alley was well established. When shop owners complained that it was "unsanitary and disgusting",[5] the alley underwent a full cleaning. The gum graffiti survived two full cleanings in the 1970s.[3] In 1996, the Business Improvement Association unsuccessfully attempted to have another alley cleaning.
But.... The rest of downtown SLO is very cool! [
