Those high school fields are nicer than any fields that you will find anywhere. Those schools, and the city of Murfreesboro as a whole, do a great job with the Spring Fling. Rutherford County high schools have great facilities and when you team them up with the city facilities and MTSU, you have a great venue for the Spring Fling.
I seriously doubt that playing at home made much difference for either Siegel or Arlington. Two great teams and great programs.
