My little boy is obsessed with Boeing planes and air travel in general, so I was thinking of taking him to Seattle for his birthday to go to the Museum of Flight. He is obsessed, but still, I was wondering if there's enough to keep him busy for a few days? If anyone's been to the Museum of Flight, is it a good idea to take a little boy of 6 there, would it be entertaining or boring? How long would it take for us to get through it? Is there much else for me to do with him if he gets bored with the museum? Being a little boy, he like the outdoors, so when is the best weather so that he can have some time to run around outside?
