From the Route 66 site I frequent came this jewel:
QUESTION: (Titled 'How easy for the Brits?')
Heya - planning to do route 66 in 2 years time with my family and planning it now.... Got the 'Here it is' maps and they look fab but the written instructions look soooo confusing, don't know if its because they are written in an american kind of way that they sound difficult to follow. Just wondering how other Brits have got on doing the journey. Is it really hard to find your way if you are a complete and utter beginner (never having been to the US before and yet taking on such a huge road trip!!!!). We would most probably be doing it as a fly/drive package so I'm guessing there won't be much time for getting lost if we have to cover so many miles each day to get to that nights accomodation?
ANSWER: (from a fellow Brit)
In general, Americans are quite civilised these days, and have adopted that great English invention, The Road Sign. These are written in English, which helps somewhat - unlike, say, travelling in Wales where a totally alien language is used. If you plan to follow each alignment exactly, you may get lost occasionally - but maps and the like now cover even quite out-of-the-way places like Tulsa and Santa Fe. Failing that, just buy a compass and keep going South-West from Chicago and West from Oklahoma - the American sun rises in the East and sets in the West just like the English sun (except their's is more frequently visible). Should you occasionally need to ask petroleum station assistants for help, you will find them to be generally friendly and intelligible - even if they don't speak in BBC Received Pronounciation, no harder to understand than the average Geordie or native of Norn' Iron. So overall, for British people, I would say that the difficulty in travelling Route 66 equates approximately to a trip from Watford to Fraserburgh, via Kings Lynn and Glasgow. But with fewer Poles and Russians en route.
(Stop worrying - just GO!)
