Dutchman I don't know how it got into MS. I know there are only a couple of ways it could get into MS and those are the ways I posted about. Since no state that borders MS has CWD currently in their deer herd unless it's gone undetected, I feel very safe in saying an infected deer didn't walk across the state line carrying it. Also, the counties in MS where the infected deer have shown up aren't contiguous. An infected deer didn't "migrate" from a county bordering the MS river to Pontotoc county.
