Zebulun had always been a risk taker. Back at school, he once pushed the limits by purposely coming to class with dirty nails. This of course earned him a firm caning, but he thought it worth it as it proved him a rebel. Later in life he rode his horse at full gallop across the new railway line barely clearing the track before the Pinkerton Express roared past. But it was the now famous photograph that proved his daring-do when he was the first known example of someone smiling at the camera.
