Man, that story brought back a bad memory for me.
I had my son sitting close to me, opening day of ny gun season. An hour before dark I hear a shot ring out down below followed by a funny sound. I said get ready, I should have said "get behind the tree". Anyways, the shots rang out and were hitting all around us, some just a few yards away. I was yelling and whistleing but the shots kept coming. I believe it was a semi pistol, to many shots at once to be anything less. We bothe ducked behind trees and waited for the shooting to stop. To this day it was the scariest 5 minutes in my life. They were only 100 yards away so I knew they heard me. I contemplated firing off a couple of rounds but never did.
