I took my son (11) and my daughter (8) to the Cavanaugh Flight Museum in September of 2011 and they loved it. My son and I enjoy reading the history. It is written in a way that is easy for all to understand and my daughter loved looking at the planes and learning about the history behind them. It was a great place for them to learn about history of flight and their country's place in it. I would highly recommend going... There is some walking outdoors so if it is raining just bring an umbrella!
