OK, when I read the thread title, I thought it was going to be about Andres Galarraga
First, If you have never seen a fox, coyote, or bobcat in real life, you would be shocked at how small they are. Most coyote would be considered abnormally large if they were even half the size of a Great Dane. Bobcats and Fox are not that much bigger than a large domesticated house cat.
Second, in the last 10 years the DNR has morphed into a bunch of overweight cubicle jockeys that know very little about the 'outdoors', and spend even less time in it. Unless they can find an answer on Google, you will probably not get a correct response from them.
My guess would be that it was in fact a Cougar or Mountain Lion, and will probably continue to 'migrate' in whatever direction it was heading.
I would completely agree with your assessment of the DNR in recent years. Some are very good, but some are just overweight turds who have never hunted, fished, camped, or anything in their life. Police officers who didn't make it through the training...
On the big cat issue. This is true.... no way a coyote, fox, or bobcat could be mistaken for a great dane sized animal. None of those even get as big as a labrador retriever usually. Also... there are big cats in the area. VERY few, but there have been one or two killed a year in the last few years. I, for one, hate it because I hunt in the area and I dont think a cat would attack me, but when I walk in and out of the woods for deer hunting, it is usually dark and that is how most cat attack happen, they get walked upon while they are sleeping and just react... I know I will shoot it if I see one while hunting.
