If you get a chance, go to the airport museum. You can't miss it as it has an old Navy PBY Catalina out front. You might want to get over by the Elmendorf AFB since they have a lot F-22 Raptors stationed there. They are constantly taking off and landing. If you head south from Anchorage on the Seward highway, you can see eagles in many places.
You can ride the train from Anchorage to Seward also. Lot's of photo ops there.
Or ride the train to Whittier. Eagles and many cool things to photograph there too.
I have a page with lots of images of Alaska.
