I have never been to Alaska. I am making my first trip in the morning and will be there this Saturday and Sunday. I am taking my 10 year old son and will be staying at either the Hilton or Garden Inn in Anchorage. What is their to do in or around Anchorage, say within 50 miles or so? We like history, historical buildings, museums, amusement parks, lighthouses, castles, forts and nature photography. Know some of these may not be available of course, just to give an idea of interests. I also don't know whether to rent a car or not. What would the road conditions be in the area this weekend? I would appreciate any recommendations.
