I caught word of it for the first time in October, 2000 when Mom and I went down there for the day. 2000 marked 100 years for first book. And well, this year marked 110!
I heard from my family that the last Ren. Fair they went to in town was a huge disappointment. There were more encampments than vendors, the stage shows had very poor performances, and the prices were food were outrageously high.
