Eastern hognose maybe? I can't quite see the face. Nice to see such a happy snake. :P

It is an Eastern Hognose; I can see that turned-up snout and that dark patch behind the head that would form a dramatic pattern if it were to spread its hood, Cobra-style. It's a harmless toad-eater but these often put on a great bluff, pretending to be dangerous Cobras, then playing possum if that fails to work.

Yah, a couple years back when I was pulling some weeds, I looked down and there was this snake coiled up and hissing at me about two feet from my face. Scared the snot out of me, but it wasn't rattling and didn't strike. I figure it was probably one of these guys. Like I said though, he scared me good. I ran to the garage for a shovel but by the time I got back, he was gone. Although this guy approached me and came within a couple feet of me, he never acted threatening in a any way even when I approached him. He just seemed to be on a mission and kept moving forward.

Grabbing a shovel shouldn't be the reaction to seeing a snake anymore than grabbing a shotgun should be your reaction when you see a stray dog, even though a dog is far more likely to hurt or kill you than a snake. I'm glad that the Hognose got away.

BUT, there's a difference between an animal merely showing up, and one that is actually trying to attack you. Dogs CAN and will sometimes attack people. Snakes, on the other hand, DO NOT attack people. ALL snake bites are 100% defensive because the snake perceives YOU as the attacker. Simply existing doesn't constitute a threat from the animal that would warrant going for a weapon to dispatch it merely because it was there.
