Market Theater Gum Wall: Seattle, Washington
Renowned for its coffee culture, Seattle has become a popular tourist destination, with one notable feature being the Market Theater Gum Wall. However, for individuals who are germaphobic or easily bothered by such things, the Gum Wall may not be an ideal stop. Located beneath Pike Place Market, the wall is completely covered in chewed-up gum, with the tradition dating back to 1993 when visitors began sticking coins to the wall using chewed gum.
