I did not realize that Maryland is so hostile to gun owners. I wonder, though.......i
I understand that the advice is given through a superabundance of caution....that being said.....why would you get stopped? Personally, I have been stopped twice in the last 40 years. Both stops were warranted, one resulted in a ticket. In neither case were firearms even mentioned. If you are driving properly, why would you get stopped? Even if you had car trouble, how would anyone know that you had a firearm in the car? You do not have to tell anyone.
Realistically, how risky is it?
