How many days are ya goin for? Last time I went to AK it was in August and it ws perfect weather. Still warm in the interior but cool at the coast. Nights were cool but still had some light in the sky around 10PM and later. Like you said, there's so much to see and do that it can't possibly all be done in one trip. We spent a lot of time on the road - went to the Arctic Circle, climbed a glacier, saw the pipeline, and did some other stuff. Did a little fishing but nothing major. To do it all takes lots of time and money so my advice is to visit several times and do a little each time. I'm headed back up in January. Have fun buddy!
