The man in the first image spoke a little English and translated for me with the group.  At first he thought I was with a newspaper, but I explained that this was just a workshop.  He also let me on his horse and asked if I wanted to join them for lunch.  They worked as cowboys on a cattle ranch.  The horse he had brought today was his day to day working horse.  He pointed to men dressed with big black sombreros on dark horses and said, "Poncho Villa!"  They found these cowboys in character quite humorous.  The young man in the third image had a big smile on his face, except when I would point the camera in his direction.  Then, he put on his serious cowboy face for photos.  While I was with this group, he asked me to photograph a girl on a horse.  I was teasing him that she was his girlfriend and he blushed. The two boys in the fourth image were riding a burrow.  The cowboys found them to be very humorous to come on a burrow instead of a horse.
