I had a big one like that stretched across one of my little trails yesterday, it's a dead end and there was no way around. I tossed a little stick but it played dead the way I often see them do. Poked it with a small branch and still got no response, so I got a bigger stick and picked it up. Didn't like that at all, coiled up and acted like it was going to attack the stick, whipping its tail around and pretending to be a rattlesnake.
Moved it off the trail and it slinked away. Geez, it would have been a lot easier if it just left the first time I poked it instead of playing dead.
