Ahem. A "Boar's Head Festival", at least out here in the wilds of the Midwest, is a secular gathering of Ren-Fest types or Mediaevalists who reenact a dinner for the nobles of the Gothic or later period of time. The centerpiece of the feast was the head of a boar, baked and often decorated in some outrageous fashion to make it the most festive part of the meal.Traditionally the main course in any great feast, it is most likely to be found in the USA as a Christmas or twelfth night dish. It was considered to be a delicacy, but trust me, it ain't all it is cracked up to be! Modern feasts use a mold of the boars head to make a pastry or a pressed meat dish of some sort. (you can buy the molds locally here. Go figure!) The last one I saw served was at an SCA event, with the "Head" made of wine laced cheese with a nut covering!
Figure you will have a big meal, a lot of European based folk music, more than likely a decent wine or a fair ale to wash it down with, and a chance to see if women in this day and age can really sit in those dresses, and if the men really can wear a sword and tights without looking like a doofus.
Mikal. (I don't have tights, but I do have this nifty Viking sword...)
