You never know where you will find art. In this case, in an alley in downtown Chattanooga.
With the tall buildings, your GPS will be of limited use. Instead, use the posted coordinates to take you close. There, if you spot an alley, and in that alley you see some art, you know you are at the correct spot. Now walk down the alley and approximately 50 feet down, you should see doors on the left. The doors constitute you farthest search boundary, while the entrance to the alley is your other search boundary.
Now, what are you looking for? Well, its a container "appropriate for the location." Good Luck.
