Rutherford county resident here. Yeah, I got a sweet job offer from CAT financial, but had to decline it due to the fact commuting into downtown is a shit show. Instead, I took another offer... so Williamson county is the beneficiary of my discretionary income. I eat out frequently, buy stuff locally, and just joined a gym there because lunch time is really the only time I have to work out anymore. The point being that a solid commuter option benefits everyone.

I also know of at least one tech company that decided to put their new office in the Wilson county Lebanon corridor. Nashville would do well to do something about the infrastructure issues.
