Those are a couple of nice Cali hogs! I live in Central California, and I have shot a few nice ones, and have been up close to a few monsters like those pictured.
I recently pulled up to a bait and tackle store close to home, and 2 guys had a hog in the back of a (1/2 ton) Chevy pickup. The only reason I even walked over to see it is because that thing was HUGE. Its nose was touching the front of the bed and it's feet were hanging over the tailgate...which was down.
It was unbelievable....it was taken with a rifle, but none the less, an incredible hog.
