Right, I will do as you suggest Michael. Do not really want but thinking about to skip on going to Sequoia to perhaps slow down a bit I think...shame I did not book my holiday in US for full 3 weeks.

Anyway, what about using google maps instead of typical satnav in far west and Arizona? Anyone have an experience, internet works ok there, or should I expect cut offs around the mountains? I think my tomtom's USA maps from 2006 may not be good anymore lol
