I suspect, like the wildlife managers quoted, that CWD will turn up there as well but I make no guess about when.
It is no suprise that as states individually ramp up testing that they find what is a fairly rare condition. I.E. the more you look, the more you have the chance of finding it. Most states that trumpet they are CWD free are not looking terribly hard.
For instance the link above notes that MT has tested 4,500 animals since 1996. Contrast that to CO that tested 26,000 in 2002 alone.
Don't get me wrong, I'm not wishing CWD on any state. I just think it is likely it will continue to show up in a lot places the more people look, because I have a two bit theory that CWD is an old disease that has been around a long time. No proof just a hunch I have.
In CO the DOW samples game populations in known CWD areas. If the concentration of CWD infections gets above a certain limit (like 15%) the DOW will then cull the herd to nothing or close to it. I assume they then sample what is left or surrounding areas more frequently in the years after the cull. This is the same "technique" being used in WI and other areas.
It is a controversial way of managing CWD, but there is no cure, but there is a new live test (tonsil swabbing) although I don't know how widely used it is.
If you're lucky enough to be on private land and can leave your stand up during the off season you can tie an old piece of cloth or something of the sort to your stand. I like to use an old camo bandana that I have. That way the deer get used to the movement and eventually don't bother even looking up when there is slight movement. This may just give you the time to draw your bow or raise your gun without being detected.
