I am doing my 10th Christmas in July on the 14th and 15th. It is held in our Cultural Center in which hundreds of people attend. It is a very large facility with vendors of all kinds. My situation is a little different in that some people sit at tables around me for a while, and then resume shopping. I limit strictly Christmas tunes to 1 in 3, with the other two mixed up in many genre's and tempo's. I try to keep everything somewhat upbeat, however, with an eye on the age group.
