A very nice report! Thanks!

At Manhattan:
"In the jam, the 2-liter V twin goes into "skip fire" mode, missing every fourth fire to cool itself — a very clever piece of engineering in an air-cooled engine"
In Death Valley:

"Holding an Evian bottle and letting water splash through your thumb onto your face every ten minutes or so provides one of the greatest highs I have ever had in my life."
Summary:
"To us, it would seem entirely pointless to go to Death Valley in an air-conditioned car,or to drive through New York with no way of looking up at the skyscrapers above. We had had an adventure and had experienced a smile every mile for over 3,000 miles"
