I started this post because CheeseHead' s original post on the subject kind of turned off in a different direction.

Anyway, I can see the value of tracking collars to get a handle on how CWD might spread. Consider us in Illinois. As far as I know, all detected cases of CWD have been confined to one specific area in extreme northern Illinois. I can see how it would be useful to know whether infected deer can be expected to remain in a relatively small area or whether they are likely to roam to distant areas.
