We couldn't find the instrument-makers' showroom. Was it canceled this year? Used to be one of the more interesting permanent exhibits, everything from oudhs and pennywhistles to dulcimers and didgeridoos.
I missed the 55-year thing because I thought it was at noon so I went to the Shape Note beginners' singing at 11 and then discovered my error. (But the Sacred Cow stuff was absolutely wonderful, and I needed to sing.)
