David - I'm still trying to picture 'Ham the Horrible'. It just doesn't work.

Ham - I don't think that it is an age thig. While I am only just pushing 50, I'm no spring chicken. I get quite a few compliments, mostly from the 20 something crowd. It leads me to believe that it is regional. Either that or I am incredibly good looking - not bloody likely. :P
So I expect that it is pretty much regional. Kilts in America are definately unexpected and provoke more interest.
