Don't go to New York City. One needs a different defense mechanism entirely there. My mother's was a hatpin, but of the old style. Probably illegal now, but I don't think our finest would do anything but approve of it. And, don't cover your eyes and ears. You need all your senses to protect yourself.
Remember, Trump's a New Yorker. I have to keep reminding people of that. He keeps wondering why everyone's so offended, I can assure you that. But then again, this is the West Coast. Ask any, and I mean ANY, person from the East Coast who lives here now and they'll laugh and do your "eye roll" what they have to walk on to not offend people on this coast.
For fun:
