It was a small child figure that was a boy who appeared to be in early 1900s clothes. Knicker shorts, long sleeved shirt and appeared to have a small bowlcut (or whatever type of hair they had at the time)
I was standing in front of the white building near the children's section where they keep the maintenence items. There is a house that you can see if you look through the bushes. The hill upscales a bit and on top of that hill is where he appeared. He appeared to be standing there with his head turned to us while his body was facing the entrance road.
He stood there watching us for about 5 - 8 seconds (long enough for two camera flashes) and then when the last flash cleared our eyes, he was gone.

This is the best picture I could find. Take off the hat and jacket and you get what I mean.
