Now that this debate is back,,I must say again, these diseases seem to always be linked to,"Captive", deer. Talk about unatural conditions. Why are these deer farms and hunting ranches not banned? In an Ag;, state like Iowa, does anyone really think that some salt put on the ground or some corn sprinkled around, greatly increases deer, nose to nose, to mouth, to butt contact? With untold acres of manmade feed they all share, and untold cattle licks they all share. A few hunters are a threat,,really,,it does not compute.
