Hello Ladies and Gents,
This event is not going to fall into the history heavy category. To be honest some of the reenactors I saw last year scared me a little and lord knows my fellow docents were not authentically dressed.
If the folks who are directly responsible for presenting the history of the property are not dressed properly, you will have a very steep slope to climb convincing others to do any better.
Do you have any guidelines to follow at the property? That might be a good place to start, and then invite others who can explain the, 'whys," and, "wherefores."
