My grandfather was in the timber business and I've seen my part of rattlers & copperheads and what happens if bitten by one. The Fish & Game people tried to relocate some about 10 miles east of here, and did a couple of years ago, the people in that area got really mad about this. Some even "put the word out" that next time there will be grave consequences.
I know there are some of these snakes protected. Here is my take on the subject. I will kill all rattlers and copperheads on my farm. My children and grandchildren are protected by me and they can rest assured that I will do so.
