Photographer: Karen Hein, New York, NY. While pretty tame inside the park, guanacos have a guard that will raise an alarm if you get too close. This guard is wondering how close he will let the photographer get before he sounds the alarm! A tourist with camera is no threat, so he is fairly relaxed.
