.Mount Juliet, Mount Pleasant and Joelton will be terrible commutes for you as all would take you right through Nashville
You must live in Snooty Brentwood.
What? Why would anyone from Mt. Pleasant go through Nashville to get to Franklin? It would be about a 30 minute commute, and they would even skirt around the edge of Columbia.
Many of the Maury County schools are very good; however, I would not put the Mt. Pleasant ones in that category.
I wouldn't even think of living in Brentwood. I'm in East Nashville.
