A little clarification on that part of the law. It is illiegal only until it is registered by the DNR. After they put their tag on it, you can carry that animal in the glove compartment if you wish.

As far as transporting in open view. I drive a Jeep Cherokee, not a lot of room inside to begin with. Once ou pack the gear and everything for two guys inside the truck for a week long hunting trip thats 375 miles away form home, there is going to be NO room for a dead animal inside the truck. I made a stainless steel cargo healer expressly for this purpose.
