Here in Charlottesville there's this concern with the governing board  
that the last (and perhaps) middle waltz is a major cause of  
apprehension for the beginning dancers.  The concern is that they  
might feel left out during the waltz.
In order to deal with this the board has decided this:
Callers should ask the band to play a last waltz BUT should not  
announce it as such.  To announce the last waltz as a last waltz is  
to make the beginners feel left out.  If you don't announce it then  
everything is fine.
Has anything like this come up in your dance community?  I am trying  
to have an open mind.
