Thanks to all who replied to my query.
We have a GL1800 reserved from AZride. com (MCTours LLC).
Based on your suggestions and a couple of websites suggesting MC roads, I have put together the attached MS Streets n' Trips route.
We'll pick up the bike Sat PM and have Sunday, Monday, and Tues with the bike due back on Tues at 5PM.
It'll be my first time on a GL1800, seemed like a good chance to try one out, but it's gonna slow us down I know. I'll cut something out of the planned route if we can't keep the time line.
Now thinking about handling the heat..... I'm thinking about picking up a CamelBack. I have vented summer riding gear, but nothing like the mesh gear I've seen the southern riders wear. So with our AGATT philosophy, we'll be challanged to mange the heat. I figure lots of cold fluids, and keep the zippers open as much as possible. (close the strategic ones when we stop at diners.
I am second guessing my choice of the Honda GL, thinking a little more wind exposure might have made sense, but we'll stick with it and see how it goes.
Any suggestions, (other than buying a whole new Joe Rocket mesh outfit?)
Thanks to all, looking forward to the trip.
(We did ride through the area in July, 1982 on a R90/6, visited the north rim, etc. I remember being on US95 between Tonopah, Nevada and Las Vegas with Death Valley on our right, and it was hot; we endured, but we were younger then.
