I'm off for a week or I would get you some better info, I am pretty intimately familiar with the Roosevelt easement from Cal Gulch (few miles west of Nogales) to the border rd on the other side of the pozo's.
Ha. You nailed our exact route: http://advrider.com/forums/showthread.php?t=872817
I'm getting to that part of the RR soon.
