Gum Wall

Prague has its John Lennon Wall, but San Luis Obispo CA really classes it up.  Yes, the world-celebrated Wall 'O Gum can be found there.  And yes, I mean chewing gum.  And yes, it was chewed before its meticulous application to the wall.  Sound appealing?  The photo of the wall in "Ripley's believe it or not! Seeing is believing" didn't gag me, it mostly looks like lumps of saltwater taffy.  The inset however... people actually TASTE this chewed gum.  With their actual tongues! That inset is a photo of a licking.  The wall is in Bubblegum Alley and became a chewed chewing gum depository in the 1950's.  Imagine sampling a bit of gum first chomped in the year you were born.  No wait!  Don't! Imagine butterflies instead.
