I used to run the haul road as a pilot car. If you're going to drive that road make sure you have a working CB radio. North of Fairbanks the drivers are on channel 19. Having a radio will also let the pilot cars talk to you. If you want a windshield when you get back slow down to around 30 mph when meeting other vehicles on the gravel parts of the road. Word will get out of you don't. Some of the drivers will talk to you if you question them about where the animals are, most of us run PB to Fairbanks in 9 - 10 hours so be careful up there.
