Your festival aways sounds like a great idea, OK. We used to volunteer at a local historic site that did something similar at Christmas time. There is a village of the 1800's here that concentrates on life along the Minnesota River when the state was being settled in the 1850's. They do a "Folkways of Christmas" presentation during December where members do a living history of holiday celebrations for the various nationalities of folks who settled the area. It is really fun and quite informative. We used to volunteer for a different culture each year, because we would have to learn a lot about it to do the presentation.
