Today was a long day. We left Sun City at 8:30am, and arrived in Carlsbad, NM, at 8:30pm. We traveled in the dark from El Paso, TX, to Carlsbad. On that route, a large wild pig ran in front of our car. We avoided hitting this large pig by fast braking and avoidance steering. We were the only car on the road, so traffic was not an issue.
