You have every right to have an unloaded rifle in your vehicle nemesis. I happened to have taken mine out this weekend and didn't have it with me. I'm not sure how other people see that, but to me, it is a tool, much like a pocket knife or pair of pliers. Both of which I never go without. Just because you are equipped to roadhunt, does not mean you are.
It's just that when you don't have a rifle with you, It's inconceivable that you could be road hunting. And If you do have one, It's much harder to convince mr. warden that your not roadhunting. especially after you have been reported.
