Marking this thread for later.
Where did you start and stop, CG? I'm guessing OK to CA?
Started near Joliet, IL, covered it for about 90% of its length, went into California to say that we were on 66 there, made a U-turn (it was about 110
o there), drifted up into Utah, went to Bryce Canyon, kept traveling generally north to I-70, then through the Eisenhower tunnel, then moteled it at the closest room we could find east of Denver (in Sterling - everything was booked up due to the evacuations from the wildfires [it was over 100
o there at 10 PM when we checked in]), then to another motel east of Joplin, then home.
It was really difficult to follow it in many places; no signs, etc. What's really needed is a navigator and a photographer in addition to the person driving. Most of the time my wife was smothered in maps.
The Oatman Highway in Arizona was the most treacherous part; they don't allow anything over 40' long on it (and it used to be part of the "Mother Road"). Then you come over a hill in a corner, and WHAM! there's Oatman (no warning), and the feral donkeys are all over the road!
I need to work on the pics we took and put some of 'em out here.
4380 miles total.
