On a long sweeper in Alberta I was nailed for 155kph. He was behind a truck coming the other way and never saw him until we passed. He wrote it for a little less (150??) so he wouldn't have to haul me off. Something like $345CN. Saw only one Mountie in BC and not a one in Yukon. 5000-5200 rpm was the normal mode when getting from point to point.
