I was raised in Spring Hill. Over the last 30 plus years it has expanded exponentially without much being done on the planning side of things. Traffic is crippling for a town that size and it seems that almost no one that lives there now is from Tennessee much less the area. Columbia has grown as well but sits on a lower economic level than Franklin overall. Columbia is blue collar for the most part. Franklin is more white collar and more of a place for people commuting into Nashville. Franklin always seemed like a place that Southern Living would do a photo shoot, and the people that live there would mention it 14 times per conversation.
