I guess I am like the other Gene.  I really enjoy the building part.  Makes your heart go pitter, patter when you see that puppy in the air.  I do mostly scratch building.  Bought several plans from air-age.  I build, my wife does most of the covering.  She does however, have no interest in learning to fly.  But, she will say, do you want to go to the field and she rides with me.
