Can someone identify this snake?

[Rick10]

I was called to remove a 5 foot snake from a neighbor's yard yesterday, and here is a picture of the snake below. Can someone help me identify it? I released it in a wooded area near a lake later yesterday. It struck at me a few times as I captured it, but it was only trying to defend itself, and I had long welding gloves on so I wasn't worried. I would guess some relative to an eastern king snake, but I really don't know.
