I've seen several copies of this picture in different archives. A. J. Shields is the man on the horse, but I can't find any information on him. I've always assumed he was a construction supervisor, but I could be wrong about that. Neither he or his family are listed in the 1929 Sugar Land telephone directory.
Regardless, you get a fine view of the eastern section of Lakeview Drive as it was being developed in 1929. Someone could probably take a print of the picture to the street today and determine exactly where the camera was placed. (It's pointed eastward from a point somewhere near the midpoint between Wood Street and Eldridge Road.)
You can see KPRC radio's transmission towers in the distance (to the right). They were located at the transmission station on what was then called KPRC Road but is now known as Eldridge Road. You can just see Eldridge's home in the distance behind the construction shack.
