I have came across some in a similar way, but copper heads. Go playing in the woods, and bam right next to me while I was chilling taking a seat. 2ft copper head reared back ready to strike. Think to myself, well this is it, i am going to get bit. What am i gonna do....think think......some 2 mins (felt like forever) pass, I got my plan worked out in my head.......gonna get bit no matter what i do, grab the head and run to the house to call the ambulance.......alright prepared, turn my head towards the copper and slowly. He's gone (during some point of my thinking process).
Yep still went home (had to change the pants)
