When and if you do the CSR you will understand. Corrugations for a day or so are ok, the CSR is corrugations nearly every day for a couple of weeks. You begin to dread the swales between dunes as you know it will be severely corrugated. There is some stunning country to be seen, Breadons bluff was my favourite section of the trip and also Lake Dissapointment. It's nothing to do with wearing a badge, the facts are it is one of, if not the most corrugated trip you will ever do over an extended length of time. It not only takes its toll on your vehicle, it takes its toll on the drivers and passengers as well. Slow and steady is the only way to do it, the corrugations can't be avoided and it is a daily thing for hours on end. If I ever do it again (unlikely) I'll go very early in the season and hope the corrugations aren't so plentiful. We met many wonderful travellers along the way as well some idiots travelling at break neck speed, no different to any other trip in that regard.
