It has been a while since I checked in on the site. In September 2012 I took a trip from central Kentucky to upstate New York on the S40. I repeated and expanded the trip this July on it's replacement, a 2007 C50. This is the youtube link of a short video and stills. And yes I know there are at least two rather common spelling errors in the captions. Thank you for pointing them out.
All I can say is that if you are only thinking about a road trip, just pack a bag, kick it in gear, and go.
Good hunting
