Good thing it will likely take me the rest of my life to get as far north as NJ, so not an immediate issue for me. I did look at air horns online. Someone on here once said that a big male was totally unfazed by a marine air horn when confronted on the trail. Can't remember now who said it or where they were on the trail at the time.
However, I if I had to pick my poisons... I'll take a ranger "ticket" or whatever they could possibly throw at me any day versus a chewed up leg, arm or worse. I'm not as afraid of a ranger doing me bodily harm as I am a bear. Fireworks wins.
