We were there in 2002, but drove in from just south of Siena so I don't know how early the market started. It was in full swing when we arrived. Unless you really know antiques, it is fun, but a bit overwhelming. I know we were there at lunch time, and had already wandered around a bit before we found a restaurant. I think I had some information from the when I went. Have you checked the Archives?

Have a great trip. Lisa in Chicago
