That's the road that finally did in my driver side wheel bearing and hub assembly a year ago in early November. It is the windiest mountain pass road in all of British Columbia that I have driven. Still safer than some mountain roads in Mexico and Bolivia though.
If folks are vehicle-touring British Columbia, the Duffy Lake Road between Whister-Pemberton and Lillooet should definitely be on the list. Budget lots and lots of time to take it nice and slow.
Incidentally, that 'fishing trip' was a disaster. First, the federal ministry of fisheries shut down the salmon fishery to retention on the day I arrived -- I was hoping to harvest a couple for the hot smoker. Second, the flow went from low and clear to mud flowing through the trees the next day. Something like 120 cubic metres per second to ~800 cm/s. Oh well. One has to learn to roll with the punches on the west coast.
