Yep, copperheads are responsible for most bites here because they won't move when you walk around them and people step on them and get bit. I was setting up for a party here and backed up and bumped my heel on one of my landscape timbers.
Looked down and a big copperhead was laying on the other side of it. Never moved. I got lucky. Went in the house and grabbed my .22 pistol and took his head off. Pretty big one as you know they don't get long, just fatter.
