Wow! This reminds me of something happened to me and my running group 2 summers ago. (Where was this taken?) We were trail running, but happened to be on one of the service roads, and I did not have my glasses on. I was ahead of the group and saw, what I thought, a large stick laying across the road. One of the guys who runs the area all the time started yelling to me to STOP, STOP, STOP! He always freaks about snakes and I couldn't believe that what I was seeing was a snake....until I got almost on top of it. There was about 5 or 6 of us, and everyone was freaking out. It was HUGE and long. The snake did not move. We walked around it and I think someone took a stick and poked it to see if it would move. Which it did not. I kept looking back to see if it moved and it hadn't. I wonder if you made enough noise it would move. I know when we were all around it, it didn't seem to even notice us. (we saw his tongue moving, so we knew it was alive.)
Could you drive over a snake that big and not kill it?
