Yes, Blackie you're correct.
The Copperheads I've come into contact with are wee little critters (in comparison to big rattlesnakes), who can at times have very aggressive attitudes. Let me add, I've had some pretty severe striking and some very unassertive behavior from these critters.
I have a friend struck by a Copperhead in the thumb.
He lost his thumb, to be replaced by one of toes. It works quite well, but is rather odd looking.
I've another friend struck by a Copperhead. Who drove him self quite calmly to the hospital. Announced his bite and the hospital staff seemed (he later told me - oh, he's a park ranger) to go into hyper drive. He laughingly asked why the all the frantic fuss. He was then advised he was going to be very, very sick from the snake bite. He then immediately went into projectile vomiting...but lost no parts.
Folks speak of Copperheads like their venom is rather minor...it isn't.
Oh, given my own State Park/National Park experience as one on staff, I know a lot of stories of venomous snake encounters...
