Several times I have asked for information on riding from south central British Columbia, down to southern Arizona by following roads along the plateaus west of the rockies. It seems not very many riders try this route. I have driven through this area several times, including a couple of weeks ago. Aside from brisk headwinds, the biggest obstacle seems to be the lack of camping, and, as "pathlesspedaled" warned about his ride in west Texas, lack of good water. In general, most of the highways are lightly travelled, there are challenging grades, and the scenery is a bit boring along the wide flats. I am still contemplating riding this route, but am considering using a single-wheeled trailer in order to carry a bit of extra water, food etc. without overloading my bike. I realize it's likey to be more challenging than my ride down the west coast but on par with my ride down the Alaskan hwy. I greatfully welcome any tips or comments from those that have ridden through this area, thanks.
