Fantastic report, Nev! You guys must have had a great trip.
I spent about 13hrs on a Greyhound bus from Vancouver to Prince George in 2002 to go see my sister. She had been on exchange for six months. I think we went through Kamloops, then back across to the 97 and through Williams lake. The snow and slush made the windows opaque fairly quickly.
In 2009 I went with my girlfriend and my Dad in Dad's RV up to Whistler then back around the ferry loop through the Sunshine Coast Highway. I loved the view of Black Tusk on the way up the Whistler. I think there is a pic of it in my not riding report.
The Spruce Goose must have been a great highlight, must put it on the to see list!
