this is my home town; haven't been back in awhile so it is hard to tell what is going on now.
But , the zoo is great. The Old Post Office downtown, the Old train station that is now a shopping mall is very interesting as they kept the orginal building and worked around the interiors.
There are a lot of old buildings still left in tack, unlike Atlanta where everything is glass.
The arch is amazing; while it was being built we all took bets on would it meet at the top. Do see the movie about it's construction, that should be at the foot of one side of the arch. No one died, except for one "Hassy" that fell from the top.
