I'm in Arkansas and everyone wants to think it came from the elk. It may have.but the states to the North of us already had CWD in their wild deer herds. Crows and buzzards hit every dead deer that hits the ground. And they move the prions around. I don't think there is any realistic way to contain it, as long as migrating scavengers can spread it. It will spread south eventually all the way to the coast. I've read a bit about the disease when it was documented in AR. The Prions are very resilient and can survive time and burning. My guess is it is here to stay.
