Glad you have found your way here! Below are a few datasets of local attractions that I think will help you get better acquainted with the Upper Cumberland (though some of the data is for the whole state!).
KMZ and GPX are GPS file formats for use on GPSs and on your GPS enabled cell phone. As an Android user, I am fond of Locus Pro as a GPS app. For the Apple users, I would recommend Gaia. These aren't the only programs you can use, so if you're comfortable with other software feel free to use that instead.
