We route using and old (as new as it gets) Street Atlas, that is getting remarkable inaccurate with age. We also carry a Walmart Rand Mcnally street atlas because electronic stuff is always undependable (right now my wire is with my wife's phone, Mine crashed).
We also carry the pair of mountain directories. They are East and West and Why carry both? because when we depart, we have a plan. That plan will be lucky to last three days. Fortunately, I can change the mail hold with the internet so I can lengthen a day or two (just like I did Monday when we changed plans).
Our coach is both small and light, but I should like to look at one sometime even thought I know that many roads we like truckers would avoid.
