Erno, like I said, I've seen dozens of buck chasing doe and grunting over the years. One year I was almost in the right spot at the right time. I had no less then 6 buck chasing various doe all around my stand. I thought I was going to get dizzy turning around in my stand trying to get an arrow in one. Last year, Nov 2nd, i grunted and rattled in a big buck. He came in ears laid back and hackles bristled. He was looking for a fight but got more than he expected. But this episode was just nuts. I have no idea why he was acting so crazy.
