There has been no threat to the wall until today; however, the surrounding controversies are still prevalent. Some find it a health hazard and a disgusting view to the eyes, while others consider it a cool destination. There is even a local tavern owner who pays to keep the Alley steam- cleaned each month to keep the germs away without changing the effect of the walls.

Some Interesting Things About The Bubblegum Alley in San Luis Obispo California

The San Luis Obispo Bubblegum Alley is a one-of-a-kind renowned unofficial landmark off Higuera St. in California that roughly estimates nearly two million gum stuck on a 70-foot-long Alleyway. You might wonder now about the history behind the survival of this beautifully disgusting Alley.

Unfortunately, there has been no precise history of constructing these walls or how and who stuck these gumballs. Historians say that the Wall dates to the rivalry between the San Luis Obispo High School and Cal Poly students in the 1950s. But others say that graduating high school class created the gum wall to celebrate WWII. 

So, the real history remains sticky and clouded. Personally, I cannot comprehend the rivalry between high schoolers and college students. It sounds unreasonable and whimsical that a rivalry is just sticking pieces of gum on a wall…!!

1. Gum Alley Controversies

The agreement to allow the existence of these gum-covered walls has been highly debated since its founding. Some local politicians and the town historian find it to be an “eyesore”. But they were counterfeited by the Chamber of Commerce, stating that this part of quaint downtown San Luis Obispo has been a “special attraction”.

Nevertheless, some bubble up with joy, taking a glimpse of this unique spectacle, while others consider it a colossal cleaning project to annihilate nasty smells and unhygienic conditions. 

  • According to the Telegram-Tribune, a local pub owner called Bill Hales pays to clean the Alley once every month.
  • Even Natural Selection, a business owned by Jim Kilbride is closeby to the Alley states that the windows stuck with chewed wads of gum are scrapped off his window on Monday mornings. 
  • To be more serious, Hales and Kilbride state that it’s not the gooey gum that bothers them.

Rather the people who use this Alley are a public restroom. There are talks of setting up lights and gates, constructing an entrance, and even handing out hoses…!!

However, till now, hoses have been given to the store wonders alone.

2. Bubblegum Alley California Washed

The beauty of this Alley is its tenacity. 

It was during the 1970s when the Alley became a fully-fledged attraction when local business owners complained that the place was unhygienic with poor sanitation and was requested for a cleanup. So, the entire place was cleaned this year and once more in the 1990s. No matter what, the gums kept on returning to the place. 

Also, the leftovers that hailed decades ago were stubborn to the washes. Finally, in 1996, there was an unsuccessful attempt by the BIA to clean the walls. 

Today, there is a fair share of controversy over the wall’s existence. Some see it as a piece of art, as a nuisance to hygiene, and others find sticking the gum as a tradition. You can find shapes, faces, words, and even flowers created out of the pieces of gum.

Also, some places say “I love SLO” in various sizes and colors. Ultimately, the Alley is a place that attracts new passers-by to just watch or even replace a missing gum piece to its walls.

“Bubblegum Alley in San Luis Obispo, California, is a polarizing landmark that embodies a unique blend of cultural quirkiness and hygiene concerns. I find it to be a fascinating testament to human creativity and community expression.

However, during a recent visit, I couldn’t help but notice the overpowering smell and the unsightly accumulation of gum. While it undoubtedly draws tourists and adds character to the area, it also raises questions about sanitation.

To mitigate hygiene concerns, regular cleaning schedules and education campaigns on proper disposal could be implemented. Additionally, placing designated areas for gum art could preserve the tradition while maintaining cleanliness.

Balancing the preservation of cultural heritage with public health is key to ensuring Bubblegum Alley remains a vibrant part of the local community.”
