What a great ride, great report and excellent photos! Love it and hate it at the same time.
My wife and I vacationed in AZ a couple years ago and saw much of the same country you covered except we stayed on the roads as we were in a rental car. The whole time I was there I was wishing I was on the bike. There is no better way to see the country than from the back of the bike. It seems you are much more of a participant in the world when on the bike where from a car it is like watching a big screen TV while you play the radio, sip your drink and blast the A/C.
