http://www.springnetunderground.net/Yeah, well that operation is a local utility that does everything in Springfield, right? Telephone, electric, water, natural gas, and the public bus transportation.... right?
Not sure why you would want to go there though?
It's all going to be homed off MCI (Kansas City). If I recall there may be some ring protection to STL.
Might as well just go to some place like http://caverntechnologies.com/ where you will have less latency than going down to Springfield.
In either instance you are in the $30 - $45/Mbps price range.
Most people are in the major markets because not only is it less expensive to operate but they have more connectivity options, and better interconnects, etc.
