My experience on 89 in 5/14 was that the pavement was rough and broken up
in many places between Flagstaff and Page. page to the Utah border was OK
and once into Utah the pavement was very good.
We were in Kingman, I-40 to Flagstaff then 89. Stayed a few nights near
Bryce, then continued north. The stretch of I-40 was a rough piece of
pavement as well. However they were starting a repaving project.
All, this got lost in the translation, it wound up going to the help desk
Did you do some seminars at Life on Wheels Conferences?
