I have no idea, to be honest. What I do know is that the bucks have lost their minds and I love it! They are running does to death. My buddy couldn't even get to where he was wanting to hunt this morning because the bucks were already chasing does on this way to his stand. He just stopped and climbed a tree and saw a 4 pt and a 6 pt chasing a doe. I had an 8 pt run a doe right under me yesterday morning, but it happened so fast that I couldn't have gotten a shot even if I wanted to. He just wasn't what I was looking for (14 inch spread).
