My formative childhood was also in Southern Arizona, having lived in several locations, such as Tucson, Tombstone, Apache Junction, Papago Reservation, etc. all prior to WW2. I return frequently to those areas and always welcome the site of Pinnacle Peak and Picachco Peaks as the landmarks that I'm nearing my destination. Life was different then, I took my Winchester to school with me and hunted game to and from school. Punched cattle on the Ronstadt ranches in WW2. Speedway was a dirt road in Tucson and the big event was capture of the Dillinger Gang by the Tucson cops. I played Indians & Cowboys in the OK Corral in Tombstone, with real Indians & Cowboy buddies in my Cub Scout Troop. Horses, wagons and cars shared the roads. Most of the kids spoke at least two languages, English, Border Mexican and some Indians dialects. You traveled across the border, both ways, with no problems or concerns. Life was "Muy Simpatico."

That photo brings back some memories. I lived in Mesa in the early 70's about the time Sun City was being built. I used to hunt quail at the foot of the Superstition Mtns. I also lived in Douglas AZ. in the 60's and hunted a lot along the border. Going back in a year or two to spend the winters in NM and AZ. Probably go into shock.
