Seattle, Washington, is full of sights to see. Known for Starbucks, Seattle has grown as a tourist destination. Besides being known for its coffee culture, Seattle is also home to the Market Theater Gum Wall. If you are a germaphobe, or things get under your skin easily, then the Gum wall probably isn’t for you. Underneath Pike Place Market lies Market Theater and its wall covered entirely in chewed-up and spit-out chewing gum. The tradition dates to 1993 when visitors stuck coins to the wall solely using chewed-up gum. Considering that Emerald City is famous for numerous things, it might be best to skip the Gum Wall and visit other destinations instead.
