Thanks for the feedback.
So if I do plan on making a new city, I plan adding an airport, industrial, convention center (just like the one in Indianapolis, Indiana), and other cool stuff and fancy stuff.
View of the convention center:



And yes I've been in the Indiana convention center back 5 months ago when I was gone for Grand nationals for my marching band trip. And it is a HUGE convention center, designed for people to stay warm if they want to make a trip to the Lucas oil stadium like if its in the low 10s, its a long walk but it keeps you warm.
