In my humble opinion, the WSP can not stop people from carrying, but they want to dictate how you carry. If you are not proficient with the "long gun" or any gun for that matter, then you should not carry it. Wish I could be there on the 30th.
A gun that is not loaded or cocked is not much use. I heard that somewhere.
Squeak, you should have seen the Parade of Donuts go by! Mmmm good!
