Every year in our DNR Hunter safety class we get asked about the PTC clause.
The CO who usually comes to each class has repeatedly stated NO YOU CAN NOT USE YOUR PTC TO TRANSPORT YOUR LOADED DEER RIFLE!!!
You can transport an unloaded rifle, shotgun or handgun out of a case in areas with less than 2500 population ,and NOT in the 5 county area around Minneapolis, ST paul other wise it must be unloaded and cased in a container made to transport firearms. Not your pillow case either, a manufactured for firearms case!
This is stated in the DNR transport regs, sorry I don't have time to search them to post a link.
You are okay to carry your handgun loaded in your car, truck only if you have a permit to carry . The subject of knives never has came up, nor has rocket launchers LOL!!!
