I just bumped up the two posts on how to ID coral snakes and cottonmouth moccasins. While I can't find the original post on eastern diamondback rattlesnakes, I did find a very good thread on assorted harmless snakes that also includes some good photos and field marks on the diamondback, as well. So if you are new to the forum, or missed these posts before, check them out. It will be helpful to you if you come across a snake and don't know whether it is dangerous or not.
