SFBayou.com started providing Cajun and Zydeco music and dance information on the Web based out of San Francisco in 1994. In 2004 I moved permanently from San Francisco to Southwest Louisiana and in 2012 stopped maintaining the content of that website.
Here is the link to the San Francisco Bay Area Cajun/Zydeco Dance Calendar, still maintained by Ellen Papper: San Francisco Bay Area Cajun/Zydeco Dance calendar .
