We did in June 2011 a trip to Alaska and Inuvik (me,
michelangelu and a guy from Colorado). You can check it out on our blog: our route, pictures and some good tips. We did it in 24 days (12000km) but of course, for 8 days you have to cut a lot. I highly recommend Skagway and the White Pass but it might be a bit too far away. You can do Hyder (don't miss Salmon Glacier), Dease Lake etc.
