We just went to AK and through BC and YT and are now in McBride, BC on our way back to Portland. The trip has been fantastic and we started off knowing fuel (diesel for us) was going to be high. Knowing that and since this was a 7 week trip of a life time, we decided not to let it be a distraction for this wonderful adventure.
Prices seem to be all over the board and the highest price for diesel has been $5.75 a gallon in Ft Nelson, BC. Overall an average of $5.31 a gallon. When we got into Alaska the average dropped to $4.65. Ironically the highest price in AK was in Valdez.
The ability to follow instructions is highly underrated.
