Not For The Faint Of Heart

We had a very creepy visitor this afternoon in our window well. Our neighbor came to the rescue and managed to get it out and into this bucket. (Bret stood by while the woman next door tackled the hissing biting thing.) Does anyone know what kind of snake this is? It isn't the first one! This and the mole are a regular occurance out here. I guess that's what happens when you live in the middle of corn fields.
