blue tounge is hitting again in South Dakota. This time it is a new strain. It is killing both muleys and whitetails. A friend told me that in the White River area there is hardly any deer left. What did make it is less than 2 years old. In some areas of the state the GFP isn't doing 2nd or 3rd drawings. There are areas that didnt get hit that are still producing some good deer. not the case where I live in North centeral SD. Try calling and talking to Al at Black Hills Archery (605)394-9663. I am sure he will have the info you need.
