I've done the much shorter 12 hour trip from Prince George to Prince Rupert, British Columbia followed by the similar length ferry trip through the inside passage to Port Hardy on Vancouver Island. The scenery on both are absolutely incredible, but I still got bored. Twelve plus hours of good scenery is just too much no matter how beautiful it is. That said, I still hope to one day take the railway clear across Canada and/or the trip across the U.S. and/or the trans-Siberian railroad. However, I will make certain to have substantial stopovers to break up the journey. I will also make certain I have plenty to read or write or code; I do think it would be an ideal place to work. Hack across America, anyone?
