The Gum Wall is a local landmark in downtown Seattle, in Post Alley under Pike Place Market    Its basically a brick wall COVERED in gum. Its very colorful. There is a large pig made of metal or brass by the name of Rachel. There is stairs right by that pig, Well you go down those stairs and keep walking through this alley thing. Then you will see a colorful wall. You go up to it, and if you have gum in your mouth you MUST stick it on the wall as this is a tradition.  There is an information booth right by the ramp and the concierge can point the way.
