Wilderness Survival : What to Do if You Are Bitten by a Cottonmouth

This is fascinating, and devastating. I have a friend who was bitten by a spider in California.....he said in the emergency room he was begging them to cut off his arm man whooooooo.........people saying copperheads aren't dangerous, then someone is killed by one. Why the hell do people go near these guys, or even consider keeping them as pets? They are NOT pets. You see them, leave them where they are. Especially, I mean, if you approach one without respect then you're asking for it I'm sorry.....
