Back from my US trip, and I did find a very cool museum to visit, the Cavanaugh Flight Museum, north of Dallas.
A great place to visit with some superb WW1 aircraft, all flyers! Enjoyed wandering around for a few hours! I took loads of pics, a few below. If anyone wants to see the rest, here's the link to my Photobucket album
