I visit rural Vigo County every once in a while and I have heard some activity on the DNR VHFs as recently as this last fall (November, maybe?). They were running the names of hunters (presumably) and coordinating activities with other officers. I can't remember what frequencies I got hits on, but I know that they were part of the DNR VHFs. It does sound like they conduct most of their business on SAFE-T (I have a BCD396XT), but I always monitor DNR VHFs because I never know what I will hear. I should mention that the few times that I have been to Vigo County this winter I don't recall hearing any activity on the DNR VHFs, but that could be normal for the winter months.
