weeeelll, the body sans head isn't very dangerous, but the jaws can snap shut and fang you a good one and that's where they keep their go-go juice. I really don't have an issue with snakes in general, but I know my long-toothed varieties and have a better than healthy respect for them and know how to avoid them.
Moccasins on the other hand are aggressive territorial and mean tempered buggers who need to keep the heck away from me. Their venom is a cytotoxin which destroys tissue, meaning that if you do get the antivenom after being bitten, you are going to have a chunk of meat gone regardless! Simply disgusting!
