I may be the only one here who doesn't have a problem with snakes, poisonous or not. When we encounter them in the wild even if its in or near a deer blind, we're on their turf. I usually don't kill any anymore just move them somewhere away from where I frequent. That being said rattlesnakes are pretty tasty.
I am with you brother. I killed a bunch of bull snakes one day when I was a boy and my stepdad got on to me about killing snakes, even venomous ones because they keep the rats and pests in check. The other caveat, is if you keep the rodents and bunnies, and etc. in check near the home, the snakes are less likely to come around. I kill venomous snakes on my home turf, where my kids play. But in the woods I leave them alone.
Edit- I must add, it was a cool video. And I don't see the harm in hunting, harvesting, trapping, skinning, selling, etc. within the limits of the law for snakes or anything else. Nothing wrong with that. As long as they are not killed and just wasted...
