I have been born/raised in Springfield. We have about 115,000 people and are surrounded by farms. Here's the thing... I can't stand the thought that we are the "big city" to all the neighboring little towns, but I also can't stand driving in St Louis or Chicago traffic. I hate the smell of manure, and I hate large spiders, but I also don't like noise and chaos.
Springfield seems to be just right. Minimal traffic, no farm stink, city spiders, quiet, and decent shopping. Quality of life is good, cost of living is low, and salaries are decent. I'm happy right where I am.
