Slither

I was visiting a friend's farm, walking through a field on my own. I'm not sure where I was going or why I was by myself, but it was a lovely summer day, so no reason is really needed. Suddenly I stopped. There was something strange just ahead of me. A coil of some sort. In my head now, it's fairly thick and long with splotches of red, but that's probably just memory inflation. It saw me, right after I saw it, and decided not to make friends. Almost before I knew it was there, the snake slithered away. I'm not a herpetologist and it has been quite some time, so I'm not exactly sure which kind of snake it was but probably just a garter snake.
