SNAKE!

Maverick says:

We saw our first rattle snake at about mile 468. He was a big one, over 3 feet and right across the trail. It's head was dipped into a teeny stream as if it was getting a drink. We found a path through the bushes around it. Then came back around to get a second look. That's when it got nervous and put out a long loud rattle as is slithered off the trail and coiled up into striking mode. We never wanted to aggravate it in the fist place so we moved right along.
