Sorry Randy, but I disagree with you. Appearance judging IS part of the nats. Rules weren't mentioned, and I feel it was a very natural question for someone not in the know to ask.
Seeing those beautiful planes at the 180 building is the premier event to many who may, or may not be there for the first time; and it is quite a spectacle. (sp?) Thus, part of the nats that needs to be highlighted, at least in my opinion and definitely involves appearance points.
For any who may be interested, one year I flew my (very) old Ephesian and had my verry own row there! Yup, it was about 4 feet behind EVERYONE else. I think I got 8 points!
