I have been to Alaska in the summer, and can assure you the wx is superb. On top of this, in june & july you get almost 24 hours of sunlight! (I think you get 4 hours of twilight but it never gets entirely dark).
Many people who live outside the major cities own an aircraft because there is simply no other way to get around....they are totally cracked in the head, landing on roads or wherever takes their fancy
I would imagine you require a gun as there are more bears in alaska per square mile than anywhere else in the world!
If you get a chance do it, I think its one of the most stunning places on the planet, and the people are very friendly.
