Very nice for the money spent. Good to know: not air conditioning if you plan on going in the summer. Takes about 2 1/2 hrs if you take your time. Quicker if not interested in reading about the exhibits. Located at an active airport with a great little reataurant on the grounds which has great food, and a Vietnam war museum, both within walking distance. Free parking. Spent from about 11:30-3pm just in that area.
