I saw one on the road once, my Dad stopped the truck and we went to look at it. Dad said pull off his buttons. I replied what if he isn't done with them yet? Dad said he's dead, to which I replied OK, you stand on his head while I get the buttons (rattle) I still have them somewhere. I got brave and wanted to keep the skin but the females wouldn't allow it in the truck. I read you can preserve the skin with antifreeze.
