Agreed. The people setting up would look strange. I'd proffer in most towns of decent size the police would be all over them. On the positive it might be entertaining to watch the hijinks. I am not saying anyone here is a wackjob or anything of that nature mind you. I'm just saying as a bystander thats what it would look like. OR it might look like homegrown terrorists forming up (pick your poison on that one-KKK, neonazis, jihadis etc.).
Now if those guys all came dressed up like the Continental Army, that would be kind of cool.
But then it would be a reenactment and not a protest or whatever this is supposed to be.
