The Chattanooga Choo-Choo of Death!
In downtown Chattanooga, TN, located inside the northern terminal for the free electric shuttle, known as CARTA, is a series of 7 3D art / paintings focusing on local attractions. This image represents the famed Chattanooga choo-choo. I am only kidding about the "of death!" part because the spikes were added to prevent birds from perching there.
Here are links to all seven images, if you want to see the others.
