" how do YOU think CWD got here in Illinois?"

I'm of the belief that CWD has always been around, but it's not near the problem it's made out to be. I live on the Illinois side of the IL-WI border and when it was first found just north of me years ago, both state DNRs overreacted by not only allowing, but encouraging the harvesting of way more deer than should have been. The conspiracy theory in me thinks auto-insurers were behind it in order to thin the herd, and reduce claims related to people hitting deer with their vehicles.
