I have been to parties in Canada, where the rifle came out as a tribute to the New Year, this right in town. But neighbours knew the good character of who lived there, and knowing where the shot came from, there was never any problem. I never recall this happening in the area we camped over several winters, 200 km south of PV. In fact, aside from campers that also included visitors to this beach area from Mexico City and Guad, and even Manzanillo, New Years Eve was fairly quiet. There was little to no electricity anywhere near the beach, so the locals were three km away. Even at Santa Anna, where the noise seemed to go on right through the night, with the same loud popping sounds predominating, I can't recall hearing the sound of a rifle, so maybe they were handguns.
