Yup, it's the body farm in Tennessee. (University of Tennessee) I've seen shows on it before, but I don't know if I've seen this particular one. Although not for the faint of heart, it's very important study and contributes greatly to forensic investigations because it simulates so many conditions in which bodies can be found. Helps to determine time of death and so on. If I remember correctly, they also have the largest collection of bones... he's an expert on that stuff too!
Argh... I remember one poor gal they had decomposing in the back seat of a car... let's just say she left her scalp behind when they removed her from the car.
