I know I'll catch some grief over this, but it is
own opinion....I consider ALL snakes to be "armed and dangerous."
If I allow myself to get close enough to see that it's definitely not venomous, it may get a pass. Otherwise, I'll light it up.
Snakes are the one thing that'll make me scream like a girl and run the 100 meter dash in about 3 seconds flat. Being born and raised in South Texas, you would think I wouldn't have this phobia but I do. I'm not a complete coward, though. I've jumped out of airplanes (for sport), rappelled out of helicopters, fought "rip roaring" house fires, and handle deadly pathogens for a living. Just don't ask me to get too close to snakes.
