I haven't been to their museum but I went to a show where they had the Gerber heir Cobra. They do a nice job of preparing cars and also have their own racetrack they promote events at. I think they would be a good spot for a Shelby museum in addition to the one in Colorado.
The Ford GT guys were out there last year. From what I was told there was a lot of paint damage after running on that track. Lots of gravel on the track surface.
