Dan's comment on another thread reminded me that going to a Ren Faire is regarded in some quarters as being cause for shame. Before we go any further, I should admit up front that I have been to a Rennaissance Faire not once, but on TWO occasions in my life.
I'm not entirely sure how Rennaissance faires got their name, but suspect it may have something to do with the fact that some of the participants wear some articles of clothing that resemble garments worn during the Rennaisance period. Beyond that they seems to be a strange admixture of Grateful Dead, New Age and SCA sensibilities. Lots of folks hawking their wares at these events to finance their activities: daggers, home made jewelry, herbs and essential oils, majicke (if you have to ask....), and faux ren foods (e.g. "rat on a spit"). In terms of historical accuracy, there is little about RF's that have anything to do with reality. On the other hand, I can see why some folks think they're fun (in much the same way that Mskis can't comprehend).
