Bubblegum Alley

Story

The gum has survived two full cleanings. That's the thing. In the 1970s, local shop owners pushed hard enough that Bubblegum Alley got scrubbed — twice — and within months the walls were coated again, pink and green and silver-gray, thick as relief sculpture. A 1996 attempt by the Business Improvement Association to clean it a third time went nowhere. The alley, it turns out, is harder to kill than the people who hate it.

No one knows exactly when it started. The San Luis Obispo Chamber of Commerce points to post-World War II graduating classes leaving gum as a kind of territorial signature. Others date the tradition to the late 1950s, when the rivalry between SLO High School and Cal Poly students needed somewhere to land. By the 1970s the tradition was entrenched — layers upon layers, a slow accretion that turned a 70-foot service alley into something between folk art and biological specimen.

At 15 feet high, the walls have been read as unsanitary, as an eyesore, as a landmark. The town historian has called it a blight; the Chamber lists it as a special attraction. Both are correct. What makes Bubblegum Alley genuinely strange isn't the volume of gum — it's that somewhere in the middle of all that anonymous chewing, actual artists showed up. Matthew Hoffman pressed an entire self-portrait into the north-facing wall at the east end, constructed entirely from gum contributed by the community. The image — Hoffman blowing a bubble — rises high above the alley floor, an oddly sincere monument built from the world's least dignified material.
