I've seen some pretty damned big wild hogs here--I saw one hit by a car in one of the rural areas west of me--but I don't think they're the same thing. Still, they're feral hogs and I'll vouch that they do a Hell of a lot of damage to a car.

If they're feral, I would imagine that at least some of them have some domestic hog in them, too, just as mustangs mostly aren't pure Spanish any more, so I suppose their could be both a lot of variation in size and a sort of loose description of what exactly counts as a razorback.

Like I said, I doubt that many, if any, get that big.
