Almost the opposite... There is only one tour I'd do again, the Carretera Austral in Chile. I've only done one tour I didn't like when doing it, an abbreviated chunk of the Western Wildlands route between Missoula and Sun Valley (way too much burnt timber, not that interesting scenery, etc.) ... felt kind of like a forced route. But I went right by the Dutton Ranch which was cool. All the others have been excellent, but the thought of doing them twice is not appealing for some reason. I've ridden some of them the opposite way (all 7 day type backroads trips in Utah). But its Utah!
