Seattle boasts with a fairly controversial tourist objective, called the Gum Wall , located on a driveway next to the oldest food market in the world in the US, Pike Place Market.
The wall covered with chewing gum by tourists and locals has been designated by TripAdvisor as the fullest germs attraction in the world.
