I was going up to a deer lease on a windy hilly road one night and as I came around a bend a feral hog ran across the road immediately in front of my car, a 65 Mustang.
The damn hog’s ridge on its back was at the same height as my hood and the length was about the same as the car,. It happened so fast that I couldn’t do anything, but fortunately I didn’t hit it.
I don’t doubt what you saw.
There are plenty of big old hogs the size of a small cow in the SE. Not sure where you are, but these are very smart animals.
I don’t know why people scoff at the idea that they are intelligent.
