It's kinda funny that people go to extremes. Too many dead rattlers can't be good, nor can too many live rattlers. Look at all the deaths and injuries as a result of ending the hunting of mountain lions in this state. When hunting was allowed, lions feared people and stayed away - yet they never became scarce, either. Now that we haven't been able to hunt them for 20 years, they kill and maim and scare and eat the family pets. Too much extremism is not good in either direction, IMO. I won't kill a rattlesnake if I can step away from it, but I've know some to be very aggresive and in those circumstances I wouldn't hesitate to kill them.
Real tree huggers are not welcome around my campfire, so don't even ask. And it is California, OK?
