I have been to Alaska twice. The first time was work - with a rest day adventure - the second time in the fall of 2008 was an inside passage cruise. The cruise was wonderful, leisurely, relaxed. The ships go into places that are difficult or impossible to get to by land. This photo was taken on a sail up a fiord. This was in early September, before new snow for the season, that is a glacier going up that valley.
My recommendation for Alaska is go, and if you get a chance to do so, go again.
