NO WAI I take poisonous snakes and grab them and bite them on my arm to increase my poison resistance I'm hardcore like that.
But seriously, I used to live in the south(Live in MN now), and I have never killed a snake in my life. I can't count the number of cottonmouths and copperheads I've had to deal with being in the outdoors in Louisiana and southeast texas. If we ever found any snake in our yard/pool, we'd relocate it a few miles away simply to get it further away from roads.
If you kill a handful venomous snakes, you're deluding yourself that it makes you or your children safer. The ones you have to worry about are the ones you don't see.
