The Ingraham Trail is a horrible, horrible piece of road. It runs NE out of Yellowknife and is the most unpleasant part of the journey. The first 30km are paved, but there are some nasty, sweeping, negative cambered corners and the only way to get around them is to grit your teeth, suck your gut in, and clench you butt cheeks as tight as you can.
The second half is unpaved, narrower, even more windy, and generally thoroughly unpleasant. 80 kmh on this would require intense concentration even with nothing coming the other way. We talk to eachother on the UHF so you know when you're about to meet a convoy coming at you, but Murphy's law dictates that you'll always do so at the worst possible moment. Here's a pic.
