Gum Wall, Seattle. Weird you say? :)
The Market Theater Gum Wall is a brick wall covered in used chewing gum, in an alleyway in downtown Seattle. It is located in Post Alley under Pike Place Market. Similar to Bubblegum Alley in San Luis Obispo, California, the Market Theater Gum Wall is a local landmark.
Worth stopping by to add to the wall or snap a few photos.
Definitely a work of "art", gum art that is... pictures don't do it justice, you have to see it to believe it.
No gum, no worry nearby stores have gum for sale!
