Corncob, we have lots of copperheads around us as well. When my daughter was a toddler and played in the woods a lot, I did kill a few. But today I just capture them and drive them to a wild area not far from here. Fortunately, my experience with copperheads is they are not very aggressive and will avoid humans if possible. I've had no problem "nudging" them away from our campsite or picnic area. Now a Cotton Mouth that decides it would be more fun to ride in our canoe through a set of rapids on the Buffalo NR, is a different matter. We made it to the bottom of the rapids without the snake, but also without the canoe, tent, backpacks, cooler, etc. We all "gathered" together in an eddy, loaded up, and took off with a good laugh. My wife that was in the front of the canoe, for some odd reason, didn't see the humor of it all. Go figure?
The only Elapidae we have in Central Arkansas is the Texas subspecies of the Eastern Coral Snake. I've only seen a couple in the wild here, down by the Louisiana border, they seem rather shy. When I worked in Central America, their subspecies were moderately common. Their jaws are rather weak and don't open very wide, so combining with their smaller heads, they pretty much have to catch a toe or finger to get a good bite. A good friend I worked with in Belize worked in the emergency ward of the national hospital and he said that he knew of a few people that were struck in the leg or back of the hand or arm by a Coral snake, but they couldn't get their mouths open enough so they just kind of bounced off without breaking the skin. Or, perhaps they were younger, smaller snakes, or just uninterested in biting someone that day? I'm sure it scared the hell out of them, but it gave them something to talk about.
