We experienced sunny skies, dust storms, and an early cold front that brought rain and cooler temps... enjoyed every bit of it. Hard to gear up for such a wide range of weather, but things worked out.
We also had fun with Apple products...my wife used an iPad app to track our progress real time that she said worked pretty good, except when we lost cell signal in the mountains, I used an iPhone on a RAM mount for both GPS w/ voice nav (3rd party product) and for tunes on the road.
The R1200R was fantastic. Even in the sustained higher speeds (out West the posted limit is 80 mph), I simply leaned down on the tank bag to get a bit more relief from my sport screen. The twisty road along the Rio Grande was custom made for the R12 ... my ride partner said, "what's the deal, you never used your brakes ? ! I said, "yeah, we talked about that some on the BMW forum"
His FJR1300 is also a fantastic bike!
