Demonic Voices???

Just so you know up front, I am kidding when I say "demonic voices." They are actually truckers... I think. As I was editing the teaching audio for the MP3 download I could hear these strange sounding voices just like out of The Exorcist. Somehow our amplifiers must have picked up a Ham Radio frequency or something. It's faint, so hopefully it won't be too distracting. Download here: "The Books of Wisdom and Poetry".
