I participated in the first Ohio open carry walk in Cincinnati. It was billed as just that: a walk, not a march. We did not walk in the street or carry banners or signs of any kind. All were asked not to wear clothes with slogans or camo. We kept to the sidewalks, obeyed all traffic signals, and left the neighborhood cleaner than we found it. It was planned before the Ohio Supreme Court had ruled regarding open carry and concealed carry -- so Ohioan for Concealed Carry (OFCC) was not an official sponser. (They became involved in later walks after the court ruling.) Police were everywhere, both visible and not. Antis tried to provoke an incident. For example, one young gal walked on my heels and grabbed at my gun several times. I did not allow her foolishness to create a scene, even though one may have been justified. One blissninny stood at the corner muttering, "Potential muderer. Potential muderer." as each person passed.
My advise is this: Do not MARCH. Do not assemble or move in a way that makes a parade permit necessary. Check out the legal requirements for a parade in advance. It's just some friends and new aquaintences going on a Sunday afternoon walk around the neighborhood. Antis will show up and look foolish in contrast.
