Lampropeltis triangulum campbelli
Those two tricks y'all are mentioning are only good for snakes in the US, when you get outside of the US they do not apply anymore. And this is not a coral snake or a scarlet kingsnake, it is a Pueblan milk snake, http://en.wikipedia.org/wiki/Lampropelti...
An easy way to distinguish between a coral snake and a king snake is to remember this rime: red and black, a friend of Jack, red and yellow will kill a fellow. Coral snakes' red and yellow bands touch and king snakes' do not.
This is not a 'Coral snake' If it was then the red rings would touch the yellow ones.
