Steph,
Just say the word and I can drop their network, I have full access to it. :)

As for the harvest festival, I believe that in current days it is considered more of a gathering for fun and entertainment, thus the kids/wee ones. In the old days it was a time to celebrate the all the crop growths and pickin's. People would spend time in the fields pick, cutting, and whatever to gather everything to bring to store for the winter and sell at market. The festival was a release of sorts, throw a party to celebrate that it was done and they could start growing more for next year. I forget where the maypole came into play as well. (Do not quote me on this now, I have forgot the details on this since it was a long time since I worked at the faire... Thanks to many, many years working at the Ren Faire, I have "relived" the harvest festivals many times over, day in and day out.

I hope this one is entertaining and fun. I assume they will be selling stuff like the farmers market does as well as other things.
