I think this is where I got some fuel too, there is a very old fuel station, not using a hand pump! but some very old pump style and a small restaurant, this place was very very expensive, I took only $50. Then you go some miles further and there is a newer place where fuel is a cheaper.
In between Dawson creek and Fort Nelson, this place is also very expensive, I stoped over and the guy came out to fuel me up, It was snowing, poor guy, when I saw the price, I said no thanks, I will try to make it to Fort Nelson. So make sure you fuel up at Dawson Creek or at least Grande Prairie.
