Living in Switzerland you are presumably familiar with hills which makes the flat bit in the middle of the NT a different experience. Coming from the North of England and having lived in Seattle for many years I find the prairies are quite a nice change. To ride down a road that disappears to a point on the horizon especially if you ave a tail wind is never to be forgotten. I love it.
AND there is no right way to go, EW or WE. 2 years ago I was told by people in e.g. Ohio I was going the wrong way for the prevailing winds. I wasn't, eventually getting pushed across ND and MT. As best I can make out the NT is a coin toss with the winds unlike the TA where south westerlies prevail on the prairie (I think)
