Actually, Murfreesboro is home to one of my favorite places...Bumpus Harley Davidson. Some of the nicest people I have ever met. Unfortunately, I wore out my shirt from there, so it might be time for another trip back.
As to a LEGO store in Murfreesboro, I wouldn't hold my breath. I've found that LEGO stores tend to pick their malls based on traffic volume, and I don't mean cars. If there are tons of people and big name stores, then the odds are fairly good that you might see one in the future. I'm sure LEGO would love to get their feet into every state, but they just have to play it smart and safe. Being that I'm in the Chicagoland area though, I shall keep my ears open and if I hear anything, I'll let you know.
