Its true that SA's skyline is drab and seems disappointingly short, but remembering that SA is the 27th largest metro (not the 7th largest) helps to put it in a little bit better perspective. Its also located in a state that has three other medium to large metros that have had or are in the process of having building booms that result/ed in lots of tall buildings. That's just the mindset in those places. Compare SA with other downtowns like Salt Lake City, Milwaukee, Tampa, Columbus, which are close to SA's metro size, and you might feel a little bit better about the situation. Phoenix and San Jose (which seems laid out more like a Bay Area suburb) are the only two top 10 cities that have skylines really comparable with SA's. Dallas, Houston, Philly, et al smoke SA, thanks at least in some part to metro populations that add a lot of wealth and density.
That having been said, welcome to the forum
I've also wondered what could be done to modernize the ToA. Adding lights is definitely one way to do it at night, but I'd also love to see architectural elements added to the roof to change to profile and add some height (ala CN Tower).
