The Sticky History of San Luis Obispo, California's Bubblegum Alley

If you step on a piece, it ruins your day. If you find a chunk under your desk, it’s time to squeal. But in San Luis Obispo, California, it’s perfectly OK to chew a big hunk of chicle and stick it on the walls of Bubblegum Alley. There are even several gumball machines right outside the alley’s entrance to gather up a plethora of gumballs before entering.
