Hogs honoring a bay

We've had them rally on us a few times and like was already said it's a beautiful noise.. Had it happen one night in a huge cotton field. My dog had a shoat caught in the middle of the field and they starting coming to him. I don't know how many it was but it's the only thing you could hear for awhile. Finally the calvary arrived and they started scattering. There was hogs of all sizes darting in and out of the rows all over the top of me. A few smaller ones ran right into me.. When it was over we only ended up catching one hog. I think it was the same shoat the dog had caught at first..
