Dear Mayor Burke, you are an idiot. I have lived all over the world. I have lived in Europe, the Middle East, and various parts of the US. Any city of a certain size has a public "green space". Some public parks are lucky enough to have an historical landmark. I can think of only one, in all of my travels, with an historic treasure. That would be the Delta Queen in Coolidge Park. She is free and open to the public, and her staff are very accommodating.
There are tour groups that will plan entire vacations around steam engines (the Delta Queen or the Chattanooga Choo Choo) or historic landmarks (see above) or riverboats. The tourist money the Delta Queen brings into this city is important. No, not everyone will stay on her, but all of the hotels, restaurants and shops will benefit by her being in Chattanooga.
If you must get rid of a n "eye sore" what in the blue thunder is that broken down barge doing still sitting on the river? The "three more months" ultimatum ran out on that in 2012 if I'm not mistaken.
