I have to agree with you the NSRM is world class. We visited it this May and saw the roll out of the McKeen car. It was worth the trip to Nevada just to see the museum. The ticket price was very reasonable and the exhibits were simply outstanding.
The museum has a great location right on a major highway. The people there were very accommodationg and the shops were impressive as well.
It's a shame that the State of Nevada will fund things that are absolute crap and stiff a world class institution that raises a lot of it's own money and has a tremendous amount of volunteer support that makes it happen.
