McCallum is a total tool with his statement.

As far as carrying modern firearms in a vehicle during a muzzleloader season is concerned, it is completely legal. One hunter held a bear tag, and brought that rifle just in case.

I have also brought modern rifles in my truck along with me on ML trips, as I have shot coyotes, and also have had elk tags (modern firearm) in an adjacent or the same unit that I was allowed to hunt deer in with a ML. 200 miles away from home there is rarely a handy gun locker available. These guys were from Shelton, 50 miles away from home. Whenever hunting with a modern, I always placed my orange vest on first when I stepped out of the truck.

You can't hunt from a truck, so your hunt begins once you step out of the vehicle.
