Just as if you are planning to gross Australia's Nullarbour Plain, you should plan for a minimum of 5 days driving, and that’s if you plan on driving without stopping to adventure anywhere.
As with a Nullabour crossing, thoroughly prepare your vehicle for the road trip. You might like to take some reading matter, besides a map.
Author Cherime Macfarlane has written a romantic road trip book that would be ideal reading before, or during the evenings while on such a trip.
About the book, Death Wish by Cherime Macfarlane.
The road from Alaska through Canada doesn’t need a map.
The road from death to life is complicated for Colin and Maria. There are detours and chasms that can break them both. A dead man they both loved is the only thing they can cling to.
Death Wish tells their story against the backdrop of the Alaskan and Canadian wilderness. If a trip to Alaska is too far for you, do a little armchair exploring, I love Cherime Macfarlane's Alaskan stories.
