I told another guy to treat it as a convention/social and have fun and talk to people. See what other people have done at protest and make it your own. This is closest thing to my flag pole I use I just duct tape and zip ties to hold 3’ x 5’ flags in place then

You could buy an American flag to fit into most protests.

I do carry a painters mask with me for tear has and bottle or water would be useful to cool down canister, or a cardboard box to contain the gas.

I bring gauze and tourniquets just in case but never needed to use them
