The coral snakes we had in Louisiana are the most venomous, but thankfully among the most docile. Water Moccasins aka Cottonmouths have a reputation for being aggressive and I have encountered a few that lived up to that reputation.
The one I fear here is the Common Death Adder. They dont retreat and if you come across one you have probably woke it as they are nocturnal. Have only ever seen one and that was in a woodpile. They like to lay in wait and ambush - I got the heck out of there asap.
Nice chatting with you :)
