When I was a kid I lived in Texas,Arkansas,and Oklahoma. We had mocassins,copperheads,and rattlers. I've seen some aggression from mocassins. While you are messing with snake #1,snake #2 might be interested in you. But mostly,they all want to slither off. Copperheads can be bad because they will live around your house and they hide where you don't expect them.
I've seen a lot of rattlers in Colorado.
If I run across one in a ranch yard,or behind a shop,or where they represent a real hazard,I'll eliminate the hazard. Snake bites can be an awful experience.
If I'm in a prairie dog town,or walking a trail.etc I just leave them alone. Its really no big deal to walk around a snake. Its easy. Just seeing a snake does not require a confrontation.
I've seen folks go into some primal hysteria over the sight of a snake. I don't get it.
40 years ago,when I still killed them, I figured out to just pin their head,a rifle butt will do,then with my Buck 110,I'd just cut the head off.
If you can't head shoot a snake from 6 feet with a ,22 shooting lead bullets,you ought to get some practice.
Its not hard.
I sometimes walk a trail I expect to hear tails buzzing,and I can generally see two or three rattlers. Part of the scenery.
When I was walking that trail regular I had every chamber of my 44 spl snubby loaded with 200 gr jhp. No snake shot. I saw a mountain lion on that trail who showed no fear of humans. I'm not interested in hunting mountain lions,but I do have a line the lion ought not cross. Scared people can be dangerous.
