What do you define as a TRUE CITY?
Atlanta is a city in every sense of the word... what do you mean exactly?? We are not lacking in architecture or in arts. If you say so, then you must not get out into the city much.
ASO hall will just be the home of the ASO and will be located in a dark alley between two tall skyscrapers... not the most appealing place for the building which looks spectacular (and expensive). Would be nice if it had a nicer location, next to a park, a body of water ( alas, we do not have Sydney Harbour in atlanta) ... i guess best option is to be perched high above 75/85 so truckers and commuters can see it from the road.
