Is there any law prohibiting wearing a vest at this event? Anyone have a group trip going?
You mean like a tactical vest? No, in fact they are encouraging people to bring their full loadout. Just as long as you transport if there in a legal fashion and no magazines touch rifle while OC's. They are also asking people to use chamber flags in their rifles.
I don't know of anyone else going. I am up in the Harford county area and wouldn't mind commuting down with others. PM me if interested.
