An unusual sight

When driving home from dinner we stopped our truck as we saw the 'Pitchfork' llamas lined-up single file.

There are about 60-70 llamas lined up on alert in this photo.  You can barely make them out.

Strange to see them line up this way.

Everyone was on guard...that's for sure.  They were calling out with grunty type noises.

We couldn't see what the problem was.  Ears up, ears back, ears up, ears back.

This was the main llama.  He just got up from rolling on his back for some time.  I haven't a clue what he was rolling on or what that behavior meant to all of the rest of the llamas.  We never did figure it out.
